ok so the bass will not eat the crappie young but will eat their own? The crappie will eat anything, including bass young? So no crappie at all in the pond would be good?

Our house framers told us that they had gone to a neighboring pond and put what they caught into our pond! Didn't tell us about it until they had been doing it several weeks. Stealing from the neighbor's pond! They were the ones who put the crappie in. So we need to get them out?

Thanks
