The flowerhorn: a fish made by people, for people

Bred in Malaysia in the 1990s, treasured across Asia as a bringer of luck, and loved by keepers everywhere as the aquarium fish that bonds like a dog. This is its story.

What is a flowerhorn?

A flowerhorn is a man-made hybrid cichlid. No river in the world produced it. Breeders in Malaysia created it in the 1990s by crossing several Central American cichlids with the blood parrot, itself a hybrid from Taiwan, then selecting generation after generation for three things: a big domed forehead, bold black markings along the side, and color.

The Chinese name, 花羅漢 (huā luóhàn), says a lot about why. Huā means flower, for the patterned markings. Luóhàn refers to the arhats, the enlightened saints of Buddhist tradition. The fleshy hump on a mature fish's head is called the kok, and in much of Asia it is read as a sign of luck, longevity and wealth.

That is only half the story. Plenty of people who don't care about feng shui keep flowerhorns for a simpler reason: this is one of the most interactive fish you can own. A settled flowerhorn learns its keeper, begs at the front glass, follows a finger along the tank and, with patience, will eat from your hand.

Why this site exists

We have kept, sold and talked about flowerhorns at Pet Zone Tropical Fish in San Diego since 2007. The same questions come up at the counter every week. Where did this fish come from? Is it natural? Why does my grandmother say it is lucky? Why does it recognize me and ignore my roommate?

Flowerhorn Hobby is where we answer those questions properly, with the history, the breeding, the culture and the care in one place. It isn't a store. When you are ready for a fish of your own, our flowerhorn shop at flowerhorn.co ships nationwide, and our San Diego stores keep them on the floor.

Common questions

Is the flowerhorn a natural species?

No. The flowerhorn is a hybrid created by aquarium breeders, first in Malaysia in the 1990s. It has no native range. The wild flowerhorns found in parts of Malaysia and Singapore today descend from fish that people released.

What does “flowerhorn” mean?

It is a loose translation of the Chinese name 花羅漢 (huā luóhàn). “Flower” refers to the patterned markings on the body, and “horn” to the hump on the forehead, which keepers call the kok.

Why are flowerhorns considered lucky?

In feng shui, fish and water are tied to abundance. The flowerhorn adds a head hump that resembles the domed forehead of Shou Xing, the God of Longevity, markings some owners read as characters or numbers, and red and gold colors associated with fortune. Our feng shui guide covers the details.

Can a flowerhorn really recognize its owner?

Keepers consistently report that flowerhorns treat their owner differently from strangers, greeting one at the glass and flaring at the other. Research has shown that at least some fish can tell human faces apart, and cichlids are among the most behaviorally complex fish in the hobby. See the fish that acts like a dog.
