I have adults of both, and although I would love to get one of my bullheads out, I don't see it happening very easily. Catching fish out of a 1000g tank is not very easy lol. The sunfish are all in a 75g getting ready to go out to the pond, so no problem catching those out. I will say that it is much more rewarding to catch them small and raise them up. Longears should be pretty abundant up by you and bullheads as well. Just gotta find places to collect.
