Went to my fav lfs today and they had a marmoratus tsn hybrid at about a foot long. It was really sweet. I have a marmoratus and from what I know they get about 2-3 ft long. My questions are how do they cross all the different combos of cats? Do they naturally breed like dogs? As long as it is a catfish about the same size they might breed? Or is it test tubed. Also how do u expect size when they mix a cat of 2 ft with a cat of 6 ft?
