I'm working on growing out several pumkinseed with the aim of doing this. It will be rather lengthy though, as it takes several years for them to reach breedable size. Also, you will need plenty of tanks, and large ones too, as the male gets very agressive during breeding time, and will need to be seperated, and the female will be killed if left in the tank to long after breeding. You can also expect alot of fry, I don't think they will be hard to raise, but you will need to use small live foods at first, such as brine shrimp naupli, cyclops, daphnia and the like. You can also hybridize different centrarchid species together, like a bluegill and pumpkinseed together. But, that is a matter for personal taste, as some people are appaled at hybrids.
