I hear ya, I was talking about public aquarium size, not home aquarium sizes. I have never seen a nut Dovii in a 5,000 gallon tank, I have seen more than a few calm ones in those monster tanks. My Dovii did not calm down one bit know that he is alone, I guess since he can't beat on a female he takes it out on me every chance he gets. I do agree that it will vary with each fish, although teh majority of Dovii are nasty.
So true aswell
