frontosa

Cyphotilapia frontosa



The king of Lake Tanganyika, this showpiece can attain lengths over 12 inches! "Fronts," as they're affectionally called, are by far the most popular tanganyikan cichlid. It's not just their impressive size or elaborate fins alone that make them so popular among aquarists, but rather their amiable and outgoing personality (not to mention that good quality fry are always in demand). This fish is like a puppy - after a short acclimization period, they'll eat right out of your hand. Wild specimens are just as gregarious as tank-raised individuals, which is a rare trait among piscovores. Despite being less active and non-aggressive, they excitably greet their owner with the same type of enthusiasm as mbuna.
Cyphotilapia frontosa ''Kigoma'' maleFrontosa are characterized by a white (or blue) body, adorned with either 6 or 7 black, vertical bars. Adults develop a large cephalic hump, with that of males usually being more pronounced. The hump is a large fatty deposit that rests atop a dorsal muscle that tends to extend forward. The hump develops and increases in size with age and is usually a sign of sexual fecundity. Their fins become more elaborate with age as well. There is nothing quite like the sight of a 10-year old frontosa with his long fins waving gracefully below and behind him.
Frontosa are found in many different locations in the lake, but always in the deeper portions along the coastline - 10-50 m (30-170 ft). Like many sedentary animals (e.g., tortoise), Fronts have an unusually long life span of over 25 years. This sedentary behavior has probably been the impetus for the development of several geographic variants. The ones pictured on this page are all from Burundi. Other geographical races come from Kigoma, Bulu Point, Mpimbwe, Samazi, Kasanga, Chaitika, Kapampa, Kavala, and Zaire. For a detailed description of their differences, visit the Frontosa Variant Map. Many other varieties exist, but for now they are considered to be junior races of the ones listed above and documented on the Frontosa Variant Map.
Cyphotilapia frontosa is a monomorphic species with little or no difference between males and females. Males usually have a larger hump than females, but this characteristic is by no means a garauntee. Frontosa can only be sexed reliably by venting, and even this method cannot always be trusted. Venting frontosa accurately requires experience. Males also tend to be larger - they can grow to over 12 inches while females are lucky to reach 10 inches - but this too is not always true. In short, be cautious of any one ready to sell you sexed frontosa; make sure they're experienced and reputable.
As already mentioned, C. frontosa is a lethargic and slow-moving fish. Even in the lake they don't expend much energy in hunting down their food. Nature has endowed them with a unique trait which gives them an advantage over their prey - Fronts are nocturnal feeders and don't require much light to wake up.
Cyphotilapia frontosa ''Kigoma'' femaleFish make up the majority of their diet, Cyprichromis species being their primary target. Cyps spend the day in large schools (numbering in tens of thousands) in the upper water column, but at dusk, they descend to the bottom where they hug the substratum. Fronts, still awake and alert, easily scoop the unsuspecting Cyps up by the mouthful. Because of the ease with which they are able to feast upon the Cyps, frontosa don't have to spend much energy chasing their food, a chase they would certainly lose to the agile Cyps during the day.
In the tank, this cichlid can be fed small feeder fish (live or frozen), mysis, shrimp, krill, and worms. Pellets are also a good food, but flakes should be avoided after they reach 4 or 5 inches in total length. Flakes will either go ignored or get too messy and are not adequate to bring them into breeding condition.
In the wild, frontosa live in large groups called colonies. In the aquarium, they should also be kept in larger groups, although they can be kept successfully in groups as small as four individuals (1 male:3 females). You'll have the best luck keeping only one adult male, and if your colony is larger, a second, subdominant male who will eventually replace the alpha-male. If you're growing your Fronts up, the "best" method is to acquire 12-15 individuals (all unrelated and from the same race) and put them in a tank of their own.
Of these 12 or 15 fry, half will probably be female. It will be a solid three or four years before they will reach sexual maturity, so we have time on our hands, and what we want to do with this time is weed out the males. As time progresses, the largest of the group will be a male. Sell this male off. Cyphotilapia frontosa ''Kigoma''In another six months' time, do this again, selling or trading the largest Front. Repeat this practice every six months or so until you are left with five or six Fronts. By now, all your males should be gone. You can verify this by venting them (i.e., checking their tubes). After three to four years time, they'll be ready to start spawning. When they are, buy yourself a beautiful, adult male and make him your stud. It is not hard to find large, healthy adults. Wild-caught males are usually available as well, at reasonable prices. The reason for doing this is to ensure that your male is of different stock than your females, which will help to ensure good fry with fewer deformities. This is important if you plan to sell your fry.
The tank should be decorated simply with a few rocks, which are important to give these shy cichlids a sense of security. Don't overdo it with lots of rocks or sharp rocks. These fish move slow until they get spooked - then they are lightning fast and very clumsy. The alpha-male will be your largest and oddly enough, shyest of the group. He will need a cave, but the females do alright in the open. While not always a success aethestically, clay pots can be used to create caves. Lace rock works well as does slate if placed on its side to create alleys and secretive coves. 40 gallons will work well as a grow-out tank. For a colony of 10 adults, a 125-gallon tank or bigger is recommended.
Patience is necessary if you plan to breed this wonderful fish. Three to four years are required for a 1-inch fish to reach sexual maturity. Sexually active males turn Cyphotilapia frontosa ''Kigoma''blue, especially the snout region. He will select an open, yet secluded area which is only weakly defended. When he has a willing female's attention, he will slowly pass over the spot with his fins folded. Spawning is very inconspicuous - no shaking, no flashing of fins, or sparring with conspecifics. As the male passes over the selected spot, he releases his milt, showing the female where to go. Some have hypothesized that the milt may serve to encourage the female to lay her eggs. She will then pass over the spot in the same manner as the male, slowly and with fins folded. After dropping an egg, she will back up - not turn around - to pick it up. She will repeat this procedure, "rocking back and forth" four to six times. Apparently, the male's milt is powerful enough to fertilize eggs several minutes after it is released.
Broods number anywhere from 20 to 50 fry, and maybe even as high as 80, depending upon the condition of the female and the variant. Females will hold for a period of 5 weeks. Fry should be separated and raised apart from the adults. Any small fish (under 3 inches) is regarded as food by adult frontosa.

The Polypteridae are primitive, snake-like fish from Africa. They are predatory and essentially carnivorous, but largely opportunistic feeders. They are able to breathe air via a lung-like modification to their swim bladder, and can travel over land using their strong pelvic fins. For this reason, a tight-fitting lid is recommended for the aquarium, to prevent any escapes.

The are two genera: the genus Erpetoichthys contains only one species - E. calabaricus, known as the Rope or Reed Fish. The other genus contains the Polypterus species (bichirs), of which there are more than a dozen species and subspecies described .


Erpetoichthys calabaricus
Scientific name: Erpetoichthys calabaricus (Smith, 1865)

Common name(s): Ropefish, Reedfish, Snakefish

Origin: West Africa, Cameroon and Nigeria

Max reported size (TL): 960mm (36")

Description: This fish is very elongate, and lacks the pelvic fins found on the Polypterus species. The dorsal surface is olive green to brownish, with the ventral surface being a lighter yellow-orange colour. There is a dark spot on the base of the pectoral fins. The max size quoted above is unlikely to be seen in aquarium specimens.

Comments: Ropefish are sociable with their own kind and intraspecific aggression is not generally observed. They are also safe to keep with any other fish which are large enough not to fit in their mouths.



Polypterus ansorgiiScientific name: Polypterus ansorgii (Boulenger, 1910)

Synonyms: Polypterus ansorgei

Common name(s): Guinean bichir

Origin: West Africa (Guinea). Possibly distributed from Ogun River (Nigeria) to Corbal River (Guinea Bissau), although this wider distribution is unconfirmed and may arise from misidentification of P. bichir.

Max reported size (TL): 280mm (11")

Description: Greenish-black colouration with large dark blotches on the flanks. The jaws are of similar length, though the lower jaw is likely to protude slightly on mature specimens. The 12-15 dorsal finlets extend forward to the rear of the pectoral fins.

Comments: A rare bichir which appears to have a restricted natural distribution and is not generally exported for the aquarium trade. It is likely that it has been confused with other species (e.g. p47 of the Aquarien-Atlas vol. 6 shows P. palmas). The available description of this species is based on only a small number of museum specimens, and it is possible that characters such as the maximum size may be innacurate.

Polypterus bichir
Scientific name: Polypterus bichir (Geoffroy Saint-Hilaire, E. 1802)

Synonyms: Polypterus bichir bichir

Common name(s): Nile bichir

Origin: Nile River, Lake Rudolf and Omo River, Lake Chad, Chari and Logone Rivers.

Max reported size (TL): 680mm (27")

Description: Dark greyish colour on dorsal surface, with irregular vertical bands on flanks. Dark horizontal bands on the sides of juveniles can usually be seen faintly in the adults. Prominent lower jaw longer than upper jaw. 14-18 dorsal spines.

Comments: The longest known and type-species of the genus Polypterus.

Polypterus katangae
Scientific name: Polypterus katangae (Poll, 1941)

Synonyms: Polypterus bichir katangae

Common name(s): None

Origin: Central Africa (Katanga region)

Max reported size (TL): 460mm (18")

Description: Olive-grey dorsal surface and whitish ventral surface. Lower jaw longer than upper jaw. 12-14 dorsal spines present.

Comments: There is a strong possibility that this species is synonymous with P. (endlicheri) congicus, as it occurs within the range of that species, and cannot be differentiated from it by meristic characters.

Polypterus lapradei
Scientific name: Polypterus lapradei (Steindachner, 1869)

Synonyms: Polypterus bichir lapradei

Common name(s): None

Origin: Most of West Africa

Max reported size (TL): 740mm (30")

Description: Grey to greenish-grey colouration, with a paler ventral surface. Horizontal bands evident on the upper surface from the head to the dorsal finlets, and extending about halfway along the side of the body from behind the gills. The flanks have irregular vertical bands. Prominent lower jaw longer than upper jaw. 13-17 dorsal spines.

Comments: This species is now a fairly common import, and captive-bred fish are also available in the trade.

P. lapradei is very difficult to distinguish from P. bichir, particularly when markings are faded, as in stressed or newly imported fish.



[b]Polypterus delhezi

Scientific name: Polypterus delhezi (Boulenger, 1899)

Common name(s): Armoured bichir, banded bichir

Origin: Central Africa: Congo river, Upper and middle Congo

Max reported size (TL): 350mm (14")

Description: The upper surface is greyish, with hints of green or yellowish colouration. The ventral surface is a uniform lighter colour. There are 7-8 dark vertical bands which vary in thickness between individuals. 10-13 dorsal finlets. The mouth is relatively small for the fish's size.

Comments: This bichir is quite commonly available. Captive-bred fish are available in the trade, but many seem to lack the more intense markings of wild-caught fish.



Polypterus endlicheri congicus
Scientific name: Polypterus endlicheri congicus (Boulenger, 1898)

Common name(s): Congo bichir

Origin: Congo basin, Lake Tanganyika

Max reported size (TL): 970mm (39")

Description: Colour can be yellowish-brown to grey. There are several dark vertical bands. Black spots are often present on the head region. The lower jaw is more prominent, extending beyond the upper jaw. Dorsal spines extend forward to the rear of the pectoral fins.



Polypterus endlicheri endlicheri
Scientific name: Polypterus endlicheri endlicheri (Heckel, 1847)

Common name(s): Saddled bichir, Red bichir

Origin: Nigeria, Lake Chad, White Nile

Max reported size (TL): 750mm (30")

Description: Irregular vertical bands are present along the sides of the fish, which do not extend fully onto the ventral surface, which is a uniform whitish-yellow colour. Black spots are present on the head, body and caudal fin. Prominent lower jaw is longer than the upper jaw. 11-15 dorsal finlets.



Polypterus mokelembembe
Scientific name: Polypterus mokelembembe (Schliewen &Schafer, 2006)

Synonyms:

Common name(s):

Origin: Central Africa, Congo River basin.

Max reported size (SL): 340mm (14")

Description: Normally yellowish-brown in colour, with large dark blotches on the dorsal surface, extending down the sides of the fish as irregular bands. There is a large dark spot on the base of the pectoral fins. 6-8 dorsal finlets present.

Comments: This species is rarely imported, and has previously been imported under the name P. retropinnis. In the description of this new species, the authors of the paper referenced below found the original type series of three specimens of P. retropinnis to be mixed. One of them was the species that has been known as P. sp. "Congo"/Zaire Green bichir (which is now designated as the "true" P. retropinnis), and the other two are the species previously known in the hobby as P. retropinnis (with broad saddle stripes) - this species is now designated P. mokelembembe.



Polypterus ornatipinnis
Scientific name: Polypterus ornatipinnis (Boulenger, 1902)

Common name(s): Ornate bichir

Origin: Central and East Africa: Congo river basin, Lake Tanganyika

Max reported size (TL): 600mm (24")

Description: The striking black and yellow patterning of this species extends into the fins, making for a very attractively patterned bichir. The head has a finely reticulated pattern. 9-11 dorsal spines present.

Comments: This is the largest of the protuding upper jaw species of Polypterus.



Polypterus palmas buettikoferi
Scientific name: Polypterus palmas buettikoferi (Steindachner, 1891)

Common name(s): Buettikofer's bichir

Origin: West Africa

Max reported size (SL): 353mm (14")

Description: The dorsal surface in front of the dorsal spines has forward-pointing "V-shaped" markings, which extend as diagonal bands onto the lateral surface. There are also diagonal bands on the flanks. Juveniles have a more dense colour pattern. The ventral surface is a uniform pale yellowish colour. Dorsal finlets have contrasting dark and light colouration. There are 7-10 dorsal spines.



Polypterus palmas palmas
Scientific name: Polypterus palmas palmas (Ayres, 1850)

Common name(s): Marbled bichir, Shortfin bichir, dinosaur eel

Origin:West Africa: Congo, Guinea, Liberia, Sierra Leone

Max reported size (SL): 298mm (12")

Description: The dorsal area in front of the dorsal finlets has irregular small spots. The ventral surface has a uniform lighter colouration. The pectoral fins are usually spotted. The membranes of the dorsal finlets have contrasting light and dark colouration. 7-9 dorsal spines are present.

Comments: There is some confusion with respect to the identity of species within the P. palmas complex, with additional variants awaiting formal description.

Polypterus palmas polli
Scientific name: Polypterus palmas polli (Gosse, 1988)

Common name(s): Poll's bichir

Origin: West & Central Africa, Congo River

Max reported size (SL): 321mm (13")

Description: Dorsal surface has large dark blotches forming a mottled pattern. Ventral surface has a uniform lighter colouration. The base of the pectoral fin has a large dark spot. 5-7 dorsal spines.

Comments: This species seems to be commonly available in most parts of the world, and may be imported simply as P. palmas.




Polypterus retropinnis
Scientific name: Polypterus retropinnis (Vaillant, 1899)

Synonyms:

Common name(s):

Origin: West and Central Africa

Max reported size (SL): 340mm (14")

Description: The species now designated as the "true" retropinnis (see below) has similarities both to species of the palmas complex, and also (in colouration) to P. weeksii. The body appears very elongated. In older specimens it is much less heavily built than P. weeksii, and does not have the large head of that species. It has been imported in mixed shipments with P. weeksii, and could be misidentified as such in the trade. The pattern is subdued and similar to the palmas species on the flanks.

Comments: It has previously been proposed that there were two subspecies of P. retropinnis: P. retropinnis lowei and P. retropinnis retropinnis. However, P. retropinnis lowei has been synonymised with P. palmas palmas.

However, there is a new twist in the designation of P. retropinnis. In the paper referenced below, the authors state that the type series (of three specimens) for P. retropinnis is of mixed composition: two are the fish known in the hobby as P. retropinnis (with broad saddle markings) - which are now designated as the new P. mokelembembe - and the third is the species known in the hobby as Polypterus sp. "Congo" or Zaire Green Bichir - which is now designated as the "true" retropinnis.



Polypterus senegalus meridionalis
Scientific name: Polypterus senegalus meridionalis (Poll, 1941)

Common name(s): None

Origin: Central Africa: Lualaba River and affluents in Katanga (Congo Dem Rep), Congo River down to Yangambi.

Max reported size (TL): 700mm (28")

Description: Uniform olive-grey colouration. 9-10 dorsal spines. Jaws appromiately equal length.

Comments: The designation of this separate subspecies is still in question - it may derive simply from a regional variant of P. senegalus senegalus.

Polypterus senegalus senegalus
Scientific name: Polypterus senegalus senegalus (Cuvier, 1829)

Common name(s): Senegal bichir, Grey/Gray bichir, Dinosaur eel

Origin: Africa: Nile basin and West Africa, including Gambia, Niger, Senegal, Volta and Lake Chad basins.

Max reported size (TL): 505mm (20")

Description: Uniform brownish-grey to olive colour on dorsal surface, ventral surface whitish. No banding on adults, very young juveniles show three horizontal bands. Upper jaw slightly longer than lower jaw. 8-11 dorsal finlets.

Comments: One of the more commonly available species, it is also one of the more active bichirs during daylight hours.



Polypterus teugelsi
Scientific name: Polypterus teugelsi (Britz, 2004)

Synonyms: Polypterus sp. "Cameroon"

Common name(s): None

Origin: Cameroon, Upper Cross River

Max reported size (SL): 415mm (16")

Description: The colouraton is different to all other Polypterus, comprising a network of black markings on the upper surface of the body, black pectoral fins and an orange ventral surface. 7-9 dorsal finlets.

Comments: This recently described species resembles P. retropinnis and also the P. palmas complex. Apart from colouration, P. teugelsi differs from P. retropinnis in a number of other diagnostic characters, mostly related to its more elongate body.

Polypterus weeksii
Scientific name: Polypterus weeksii (Boulenger, 1898)

Common name(s): Weeks' bichir, Fat-headed bichir, Mottled bichir

Origin: Central Africa: Congo river basin

Max reported size (TL): 540mm (22")

Description: This species usually has a very clear distinction between the dark greyish-green dorsal surface and the whitish ventral surface. Several dark bands are present which may fork towards the bottom. The head is relatively large, giving rise to one of the common names of 'fat-headed' bichir. This species retains external gills much longer than most other Polypterus species. There are 9-11 dorsal finlets.

Comments: The Weeks' bichir seems to have a mild temperament and mixes well with other Polypterus species. However, the large mouth is capable of swallowing surprisingly large fishes, so any tankmates must be much bigger than the fish's mouth.

Arapaima gigas

Brief intro..
The Arapaima fish is also known as the Pirarucu, and is one of the biggest freshwater fish species in the world. Its scientific name is Arapaima gigas. This fish can only be found wild in the Amazon River Basin in South America. It can reach a length of 450 centimeters (177.17 inches) and weigh up to 200 kilograms (440 lbs). The Arapaima is grey and decorated with an orange speckling at the posterior end. The scales can grow up to six centimeters long on the largest Arapaima specimens. You will find two symmetrical fins on the body, located at the posterior end.

The Arapaima is a predatory fish that eats fish, birds and any other animal that it can catch. The major part of its diet consists of fish, but since it is a large opportunistic hunter it will happily gulp down other animals as well. Arapaimas prefer to hunt close to the surface since they need to breathe oxygen from the air. This does however not prevent the Arapaima from occasionally diving very far down. The fact that this fish needs to breathe air from the atmosphere every 10-20 minutes must of course be taken into consideration if you intend to keep an Arapaima in captivity. The aquarium must be arranged in a way that makes access to fresh air possible. Arapaima is found in various habitats in the Amazon River Basin which means that you can have some freedom when you decorate its aquarium. You will find Arapaima in the Amazon River, in the tributaries and in the floodplain lakes. It lives in white water as well as clear water, and the fact that it breaths oxygen from the atmosphere makes it possible for this fish to live in oxygen depleted swampy waters as well.

Arowana

Arowana



Arowanas are freshwater bony fish of the family Osteoglossidae, sometimes known as "bonytongues". In this family of fishes, the head is bony and the elongate body is covered by large, heavy scales, with a mosaic pattern of canals. The dorsal and the anal fins have soft rays and are long based, while the pectoral and ventral fins are small. The name "bonytongues" is derived from a toothed bone on the floor of the mouth, the "tongue", equipped with teeth that bite against teeth on the roof of the mouth. The fish can obtain oxygen from air by sucking it into the swim bladder, which is lined with capillaries like lung tissue. The arapaima is an "obligatory air breather"

Classification and distribution

Osteoglossids are basal (primitive) fish from the lower Tertiary and are placed in the actinopterygiid order Osteoglossiformes. There are ten described living species: three from South America, one from Africa, four from Asia, and the remaining two from Australia.
Osteoglossidae is the only exclusively freshwater fish family found on both sides of the Wallace Line.This may be explained by the fact that Asian arowanas (S. formosus) diverged from the Australian Scleropages, S. jardinii and S. leichardti, about 140 million years ago, making it likely that Asian arowanas were carried to Asia on the Indian subcontinent.

Behavior

Osteoglossids are carnivorous, often being specialized surface feeders. They are excellent jumpers; it has been reported that Osteoglossum species have been seen leaping more than 6 feet (almost 2 meters) from the water surface to pick off insects and birds from overhanging branches in South America, hence the nickname "water monkeys". Arowanas have been rumored to capture prey as large as low flying bats and small birds. All species are large, and the arapaima is one of the world's largest freshwater fish, at 2.5 metres (8.2 ft) in length.Arowana typically grow to around 3 to 4 feet in captivity.

Several species of osteoglossid exhibit extensive parental care. They build nests and protect the young after they hatch. Some species are mouthbrooders, the parents holding sometimes hundreds of eggs in their mouths. The young may make several tentative trips outside the parent's mouth to investigate the surroundings before leaving permanently.

In the aquarium
Arowanas tend to merge in groups of five to eight; any fewer may show an excess of dominance and aggression. Some compatible fish often partnered with this fish are clown knifefish, pacu, oscars, plecostomus, jaguar cichlids, green terrors, gar and any other semi-aggressive fish that cannot fit in the arowana's mouth.

Australian species are best kept singly in aquaria.

Folklore

For the Chinese and those of related cultures, the dragon is a symbol of good luck and prosperity. In the eyes of the Chinese, the dragon fish has the appearance and majesty of the Chinese Dragon, especially the large scales and barbels.

Arowanas are also used for feng shui to bring good luck. As per the feng shui belief Arowanas are believed to possess capabilities to distinguish between an enemy and a well-wisher. It is believed that if the arowana in the aquarium shows aggression toward the visitor to house, he is an enemy; and if the fish remains calm, the visitor is a well-wisher.

Species

The family contains two subfamilies, Heterotidinae and Osteoglossinae, with all but two of the ten extant species being members of the latter. Species are given with one or more prominent common names.

Family Osteoglossidae

Subfamily Heterotidinae
o Genus Arapaima
Arapaima or pirarucu, Arapaima gigas (Cuvier, 1829)

o Genus Heterotis
African arowana, Heterotis niloticus (Cuvier, 1829)

Subfamily Osteoglossinae
o Genus Osteoglossum (Cuvier, 1829)
Silver arowana, Osteoglossum bicirrhosum (Cuvier, 1829)
Black arowana, Osteoglossum ferreirai Kanazawa, 1966

o Genus Scleropages
Red-tailed golden arowana Scleropages aureus (Pouyad, Sudarto & Teugels, 2003)
Green arowana or gold crossback arowana, Scleropages formosus (Schlegel & Müller, 1844)
Gulf saratoga, red saratoga or northern spotted barramundi, Scleropages jardinii ‡ (Saville-Kent, 1892)
Red arowana, super red arowana, or chili red arowana, Scleropages legendrei (Pouyad, Sudarto & Teugels, 2003)
Saratoga, silver saratoga or spotted barramundi, Scleropages leichardti ‡ Günther, 1864
Silver Asian arowana, Scleropages macrocephalus (Pouyad, Sudarto & Teugels, 2003)

‡This species is one of two sometimes called the Australian arowana or Australian bonytongue.
A genetic study shows that the lineage leading to the arapaima and African arowana diverged about 220 million years ago, during the Late Triassic; the lineage leading to the silver and black arowanas of South America diverged about 170 million years ago, during the Middle Jurassic. The lineage leading to the Australian arowanas diverged from that leading to the Asian arowanas about 140 million years ago, during the Early Cretaceous.
Fossil record

At least five extinct genera, known only from fossils, are classified as Osteoglossids; these date back at least as far as the Late Cretaceous. Other fossils from as far back as the Late Jurassic or Early Cretaceous are widely considered to belong to the arowana superorder Osteoglossomorpha. Osteoglossomorph fossils have been found on all continents except Antarctica.

Flowerhorns (Lou han)

The history of the Flowerhorn cichlid

The Flowerhorn chichlid is a result of hybridisation between different South American chichlids. The Flowerhorn was developed in Malaysia during the second half of the 1990s, and exactly which South American cichlids that was used and in which combinations is still a secret. This secrecy has of caused a lot of speculation and a number of more or less reasonable theories have been put forth. One of the more far-fetched theories suggests that the Flowerhorn cichlid was artificially created in a Malaysian genetics laboratory by combining genes from a Goldfish with genes from the Trimac cichlid (Amhilophous Trimaculatus). A more reasonable suggestion is that the Flowerhorn cichlid is the result of crossing many different types of South American cichlids with each other, and that different forms of Flowerhorn cichlids can steam from different South American cichlids. The most plausible ancestry is crossings between the Trimac cichlid and other South American cichlids such as Midas cichlid (Amphilophus citrinellum), Red Devil cichlid (Amphilophus labiatum) and Redheaded cichlid (Vieja synspila).

The look of the Flowerhorn cichlids available in fish stores today is however not just the result of selective breeding. You can affect the appearance of a Flowerhorn cichlid by adjusting environmental factors such as the water chemistry in the aquarium. The food you feed your Flowerhorn cichlid can also change its look. The single most important factor behind the look of the fish is however the genetic makeup formed by selective breeding.

The Flowerhorn has been criticised as an unnatural and dangerous hybrid, produced by money-hungry breeders just to make money. Others have been impressed by the hard work that is evidently behind the creation of the Flowerhorn Cichlid. A lot of the South American cichlids mentioned above will occasionally interbreed in the wild as well, but there is no doubt that the Flowerhorn cichlid has been deliberately produced by breeders. The Flowerhorn cichlids are not the result of random cross breeding. Some people view the Flowerhorn as a purely man-made creation while others compare the hybrid to all the other animal variants that have been refined by humans during centuries of selective breeding.

What to think about when buying a Flowerhorn cichlid

When you look for a suitable Flowerhorn cichlid to buy, you should consider the same facts as you do with any type of cichlid. Make sure that the fish store is well kept and that all the fish look as if they are well cared for. Also check the specific individual that you are interested in. The Flowerhorn cichlid should look healthy and happy. Do not buy a Flowerhorn that seems to be stressed in the aquarium. One good test is to see whether the Flowerhorn eats or not, since poor appetite is a very bad sign in a Flowerhorn cichlid. A Flowerhorn that won’t accept food when offered is probably ill or extremely stressed. When you bring your new Flowerhorn cichlid home, remember to give it plenty of time to adapt before you release it into its new environment.

One large question when it comes to buying a Flowerhorn cichlid is if you want to buy a young Flowerhorn or a mature one. The young Flowerhorn cichlids are much cheaper than the mature ones, since it is impossible to tell which colour pattern a young Flowerhorn cichlid will display when it gets older. If you want to keep your Flowerhorn cichlid from the beginning and watch it develop, it will require a much smaller investment. On the other hand, if you buy an adult Flowerhorn cichlid you know what you get. A lot of people believe that Flowerhorn cichlids with certain colour patterns provide great Feng Shui to the house where they are kept. If you want to own a Flowerhorn cichlid with a very special pattern for this purpose, you need to buy an adult one. If you are on a restricted budget you can of course gamble and buy several young specimens, hoping that at least one of them turn out to be a premium specimen with the right colour pattern.

Adult Flowerhorn cichlids with very desirable patterns are extremely costly. High quality Flowerhorn cichlids with markings similar to Chinese letters have been sold for several hundred thousand dollars. There has been a large hype concerning the Flowerhorn cichlids ever since they were developed, and Flowerhorn cichlids have been traded like stocks since their value can increase as the develop. Today the hype seems to have cooled down a bit and a lot of people have lost considerable amounts of money during this process. Premium Flowerhorn cichlids with a well developed hump and desirable markings are however still very expensive.

How to care for a Flowerhorn cichlid

The Flowerhorn cichlid is considered quite easy to take care of and do not require a lot of pampering from its keeper. The first thing you need to do is of course to set up an aquarium suitable for a Flowerhorn cichlid. Your Flowerhorn will require a large aquarium to do well, since this fish grows quite big and have an aggressive temperament. If you use plants to decorate the aquarium, they might be destroyed by the Flowerhorn cichlid, and plants are not necessary in an aquarium set up for a Flowerhorn cichlid. You should however decorate the aquarium in a way that creates natural territorial borders, since the Flowerhorn cichlid is a territorial and aggressive fish. You can of course keep the Flowerhorn cichlid alone, but if you want to have more than one fish in the aquarium other big aggressive cichlids from South America is the best choice. The Flowerhorn cichlid is a tough fish and can tolerate most water conditions, but it will do best in an aquarium where the pH is neutral or slightly basic. A water temperature around 28º C is recommended.

The Flowerhorn cichlid is a happy eater and you will not have a hard time trying to make it accept food. Its metabolism and feeding habits are similar to that of the other South American cichlids, and your Flowerhorn cichlid will need a lot of energy and nutrients to stay healthy and develop in a good way. It is actually quite hard to over-feed a Flowerhorn cichlid. Your Flowerhorn cichlid will accept most types of food, and pellets are a good base. This base should be supplemented with plenty of worms, crabs, shrimp, or similar types of meaty foods. Feeding two or tree times a day is optimal.

Since the Flowerhorn cichlid eats a lot, it will also produce a lot of waste products which pollutes the water. Frequent water changes must therefore be performed. Changing 20 percent of the water twice a week is a good rule of thumb. If you can only make one change a week, you should change around 25 percent of the water. You can lower the risk of poor water quality by avoiding food types known to pollute the water a lot.

Luck and Feng Shui

According to an Asian belief system called Feng Shui, good luck and harmony can be caused by Flowerhorn cichlids if they display the right colour markings. The Flowerhorn is not the only fish believed to be capable of this, and fish species such as the Arowana have been kept by Asians for a long time to ensure harmony and happiness. The Arowana is believed to bring luck since it resembles dragons from Chinese mythology. Compared to the dragons in European mythology, the Chinese dragon is associated with much more positive abilities. The Flowerhorn cichlid does not resemble a dragon; instead its hump makes it look somewhat like the Chinese God of Longevity. If the hump of your Flowerhorn cichlid grows large, so will your luck. The good luck brought by Flowerhorn cichlids is believed to affect all areas of life.

The markings of the Flowerhorn cichlid are also very important from a Feng Shui point of view. If the marking resemble a desirable Chinese letter, the Flowerhorn cichlid becomes very valuable. A woman who won 1 million dollars at the lottery claimed that she had played on the number displayed on her Flowerhorn cichlid, and circulating stories like this will of course increase the Flowerhorn hype. Some Flowerhorn cichlids display the Chinese sign for “luck” on their bodies, and these individuals are of course extremely rare and extremely expensive.

Breeding Flowerhorn cichlids

Making your Flowerhorn cichlids breed in the aquarium requires basically the same type of preparations and care that you would give Trimac cichlids or other similar South American cichlids. Keep the potential parents in a very large aquarium, and try to keep them from killing each other. Flowerhorn parents guard the eggs as well as the fry, and the fry is fairly easy to take care off. Even if you start out with prime specimens as parents, the offspring will often turn out to be a disappointment if it is certain colour patterns etcetera that you are looking for. You need to know quite a lot about the different strains and lines to successfully breed Flowerhorn cichlids. There is of course always the chance of getting lucky and producing great specimens even without this knowledge.

Flowerhorn critics

The Flowerhorn cichlid has been subjected to a lot of criticism. Some people have disliked the fact that it is an artificially created hybrid, while others have criticized not the fish per se, but the huge financial hype that was created around it. Critics claim that the Flowerhorn cichlid was created only to make money from, and that the hype is a result of excellent PR. This might very well be true, but a lot of aquarists love the Flowerhorn cichlid regardless of why it was created. A true fact is that the Flowerhorn cichlids were treated more like stocks than animals during the peak of the hype, and that people lost considerable amounts of money when the Flowerhorn bubble burst and the market cooled down.

Many people feel that man should avoid creating new hybrids. Some critics have religious motives behind their conviction, and argue that animals should be created by God, not by humans. Others point to possible environmental problems that could occur if the natural fauna was contaminated and disturbed by unnatural hybrids.

Concerned voices have also claimed that the presence of fish hybrids make it close to impossible to identify pure breed specimens in fish stores, since hybrids are frequently mislabelled and sold under the wrong name. Those in favour of the Flowerhorn cichlid have responded that this is not a problem caused by the Flowerhorn or any other hybrid, this is a problem caused by irresponsible store keepers.

As mentioned above, hybrids like the Flowerhorn might cause severe ecological problems if they are released into the wild. Animals released into environments that are not used to their presence can often cause a lot of problems, regardless of whether they are hybrids or just animals from some other part of the world. We have already seen the effects of rabbits in Australia, Water hyacinth in Africa etcetera. Regardless of wish type of fish you keep, hybrid or not, you should never ever release it into the wild!
