flowerhorn cichlid
Flowerhorn cichlids are ornamental aquarium fish noted for their vivid colors and the distinctively shaped heads for which they are named. Their head protuberance, or ''kok'', is formally termed a "nuchal hump." Like blood parrot cichlids, they are man-made hybrids that do not exist in the wild. First developed in Malaysia, Thailand, and Taiwan, they are now kept by fish hobbyists worldwide. Some hobbyists have questioned the impact of flowerhorn breeding programs and their impact on the health of the animals, and on natural fish species.
== Origin ==
Flowerhorn breeding dates from 1993.〔(''Flowerhorn 101, A Guide to Flowerhorn Strains and Types.'' )〕 Malaysians admired fish with protruding heads, known as ''Kaloi'' or "warships," found in the western part of the nation. The slightly protruding forehead and long tail of these fish were prized in Taiwanese society as bringing luck in geomancy. By 1994, red devil cichlids (typically ''Amphilophus labiatus'') and trimac cichlids (''Amphilophus trimaculatus'') had been imported from Central America to Malaysia and the hybrid blood parrot cichlid had been imported from Taiwan to Malaysia and bred these fish together, marking the birth of the flowerhorn.
In 1995, the blood parrots were further crossbred with the ''Human Face Red God of Fortune'', which produced a new breed called the ''Five-Colors God of Fortune''.〔 With its beautiful colors, this fish quickly became popular. Selective breeding continued through 1998, when the ''Seven-Colors Blue Fiery Mouth'' (also known as ''Greenish Gold Tiger'') was imported from Central America, and crossbred with the ''Jin Gang Blood Parrot'' from Taiwan.〔 This crossbreeding led to the first generation of ''Hua Luo Han'' flowerhorn hybrids, which were then followed by subsequent flowerhorn introductions.
