CICHLIDS


Flower Horn, Flowerhorn, Lump Head Cichlid, Malaysia Rajah Cichlasoma, Hualorhan, Luohan
"Cichlasoma" sp. [see "ORIGIN" below]

ORIGIN: Believed to be a hybrid between Amphilophus citrinellus and Amphilophus trimaculatum first developed in Malaysia around 1996. Some claim that the hybrid has since been crossed with the "Giant Blood Parrot" -- a hybrid of its own. Hence the Flower Horn is a completely artificial fish and it lacks a bonified scientific name.

SIZE: To 12" (30 cm)

HAB: Originally Central America, but now captive bred in Asia. Amphilophus citrinellus - Southern Mexico, Nicaragua (lakes-Nicaragua, Managua, and Xiloa; Rio San Juan), Honduras, Costa Rica (Costa Rica River and Cuba River). Amphilophus trimaculatum Southern Mexico & Guatemala (Chiapas and Huamuchal).

S: bottom, middle

TANK: A 48' (122 cm) tank with a capacity of 55 gallons (209 L) is sufficient for a specimen up to 8' (20 cm). Larger tanks are required for larger fish. The tank should be large with plenty of open swimming area. Provide plenty of hiding places with stones, cave, and roots. These structures must be well-anchored. Use live plants at your own risk -- plastic plants are a safer bet.

WATER: pH 6.5-8 (7.2), 6-25 dH (10), 73-86°F (23-30°C).

SB: A territorial and pugnacious cichlid, especially around spawning times. The Midas Cichlid can be combined with medium to large sized cichlids - small fish will be eaten. Mates form monogamous pairs and become fine parents. If the female is not ready to spawn, she may be bullied to death by the male. Keeping two mature males in a tank is not recommended - one will likely be killed.

SC: Other large sturdy fish. Cichlasomines, South American cichlids, Loricarids, Pimelodids, large Characins.

FOOD: Live; snails, fish, earthworms, insects; chopped meat; vegetables; spinach, peas, lettuce; pellets; tablets.

SEX: Males are slightly larger, more aggressive and haved a more developed nuchal hump on their forehead. Spawning season is easiest time to discern sex.

B: Similar to Amphilophus citrinellus. Increase the water temperature a few degrees to 79-86°F (26-30°C). As many as 1000 eggs are usually laid on a vertical surface (i.e. slate, pane of glass) or sometimes on rocks at the tank floor. The eggs are guarded by the female and the territory is defended by the male. The eggs hatch in 3 days and the young are moved to large, previously dug, pits where the parents continue their care. The fry can swim on their own after 5 days, at which time they can be fed small live foods. Occasionally the fry may adhere to the flanks of the parents in order to feed off a mucus sections produced by the skin of the parents.

BP: 6. Breeding is not especially difficult.

R: Flowerhorns display their best colors (and largest hump) when they are stressed (excited). Hence they are often kept in small tanks, with bright surroundings (colored gravel) and mirrors -- much to the detriment to the fish. Mistreatment of this species is widespread.
The Flowerhorn is the focus of a major craze in Asia and high quality fish fetch thousands of dollars on the market. Many varieties are available.
One of the factors behind this craze is the belief that the Flowerhorn may achieve feng-shui fish status. To date the Asian Arowana has held this title as thousands have kept Arowanas believing they bring balance and good fortune to the life of the keeper.
Many dedicated aquariasts (especially States-side and in Europe) are vehemently opposed to hybrids on ethical grounds and are quite vocal in denouncing this fish.

DC: 6. The Flowerhorn is an aggressive species which must be kept in a large tank.





Recent news

Census of marine life opens with 122,000 species
(7/1/2008) Discovering a new species can be the highlight of a biologist's career. Yet once a species enters the formal literature, complications may develop. The systen has been especially problematic because for centuries biologists have lacked the tools to construct a full and flexible list of the world's innumerable species. Using the Internet and hundreds of scientists around the world, the Census of Marine Life is attempting to take on this monumental task.

Large shark populations fall 97% in the Mediterranean
(6/12/2008) Populations of some shark species in the Mediterranean have plunged by more than 97 percent over the past 200 years, report researchers writing in the journal Conservation Biology. Several species are at risk of extinction.

Dried-up Colorado takes toll on giant Mexican fish
(6/8/2008) The Colorado River vanishes before it reaches the Sea of Cortez in all but the wettest years. Companies in California and the southwestern U.S. have diverted its once-vibrant flow to quench their thirst for water and power. Now, a new study in the April 2008 issue of the journal Biological Conservation reports that the dwindling of this major artery has changed the way some marine fish in the Gulf of California grow and develop.

Diversity in streams may brace Chinook salmon for climate change
(6/3/2008) Chinook salmon face a one-two punch. They have disappeared from several rivers in the western U.S. largely because of human interventions and some populations are threatened or endangered. Numbers of Chinook in California's Central Valley have dwindled by 88 percent in the past five years, a loss that closed fisheries for 2008 and may cost California's economy $167 million, according to the state Department of Fish and Game. On top of all this looms a second impact: These salmon will be in hotter water still because of climate change.

Greenpeace ship attacked by Turkish tuna fishermen during protest
(5/30/2008) Members of a Turkish tuna fishing boat attacked the Greenpeace ship Arctic Sunrise while the ship was engaged in a protest against overfishing. The incident occurred Friday in the Cypriot Channel and was reported to the Turkish Iskenderun Gulf Port Authorities.
