Hi. I previously posted I was sold two CAE's, unknowingly. They are both males (they have the pronounced mating horns coming out on their noses) they are both about 3" long now and have always seemed to be fighting, but then again side by side most of the time. They haven't hurt any of their tank mates, but I'm afraid for them. My question is, should I separate them and keep each one in a 29gln tank with mates, or keep them together in their own 29 gln just for them? The pet store has offered to take them back, but I feel like they'll end up being fish food if I do. I have gotten attached to them. I don't mind them having their own tank, but the fighting worries me. Is it natural??? They act like buddies, then turn around and they're fighting, or playing???? I'm so confused, any advice will be greatly appreciated!
