If your bashing on me, don't even start okay? I've never fed them ANY feeders or any live food. So excuse me, AND I've had jack dempseys and cons together before. No aggression at all. So before bashing, try to learn your facts first. I'm probably going to get this 50 gallon I have in the shed and see if I can use it to transfer the firemouths and cons. And I'm making decisions on what to do with the fish.
