So I was planning to get a spotted bullhead for my tank, although my question is, are they as aggressive as their cousins? I kept a native fish tank, common shiners,chubs, and perches. I introduced two black bullheads into the tank. All the fishes in the tank were around 8-9 inches. And the two black bullheads ended up killing all my fishes in the tank. And I dont want another mass killing spree. So anyone with experience on bullheads, I would really love your advice. Thank you for your time.
