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 color 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.
