Hello,
I have a green sunfish and two black bullhead in my tank now. I know they're both aggressive enough to hold their own against each other, but the bullhead will get too big for the tank eventually. I was hoping to replace them with some madtoms if i can find a good creek to catch them in. Most of the info i've found are about tadpole madtoms and says that they're pretty peaceful. Would anyone know if they'll get beat up by the greenie or if they'll be ok together since they have different specific niches and the madtoms will stay in their burrow alot. Of course i don't know what sp of madtom i'll find when i'm out there.
