General: 

As mentioned in Flowerhorn history, they are crossbreeding species. As a result, the majority or even most flowerhorn males are sterile, which means that they cannot reproduce. By far, a very small percent of a batch would result in fertile males whereas the rest of the batch or sterile. Since not every male flowerhorn is fertile, finding a best or perfect fertile flowerhorn is time consuming. That is, hobbyists have to wait until the fish is sexually mature and then pair the male with a female to see if the male is fertile.

Flowerhorn Breeding

Flowerhorns are aggressive aquarium species. They cannot be kept with small cichlids, i.e., African cichlids, peacocks, etc., or they will kill the small cichlids. Likewise, they cannot be kept as a group in one aquarium; they will fight each other until the strongest one last. Very few hobbyists keep them with large cichlids in large aquarium; however, it is not recommended. Most flowerhorns are raised individually in separate aquariums or with a divider between them after the size of 1 - 1.5 inches for the rest of their lives.
