its is very difficult, time consuming, space demanding, secretive, and expensive. They also use south american cichlids to create their crosses. most of the valuable ones come from over seas because no one in the US has developed strains as nice.

you may consider trying it for yourself once you have experience farming fish, chemically inducing spawning, and raising thousands of fry to adulthood not knowing if they will be worth anything.

of course in a few more years the really expensive ones will likely be common and affordable with some new strain being the expensive fish.
