I've kept wholesale bred ones so far. Somehow by accident managed to breed very nice looking barred and pink females. Though my pairs are gone and I don't miss the breeding like rabbits. I feel the urge to snatch a few from my step dad's tank since he kept a lot of them for himself :/
I've always wanted to try the calico/marble ones but I've never seen them at an LFS and I've never thought to order them. Would be a fun breeding project.
