I've got 3 juvenile Ocellaris right now. They all 3 enjoy being around each other. Is this ever going to be a problem? Will eventually 2 pair off and leave the other one? or event get territorial on him?
Should be no problem at all in a large tank. If tank bred, there are some reports you'd be OK also, but I'm skeptical. In a small tank, live caught, you'll probably end up with 2 maybe just 1.
Like stated above if the aquarium is large enough it shouldnt be a problem. If the aquarium is smaller it could be a problem with two pairing off while the other gets picked on.
