I placed 2 very small damsels into my tank and am plaining on adding my 2 clown fish by the weekend when they are out of quarintine. Just Want to make sure there won't be any problems with fighting or anything.
A regular and black ocellaris would probably be fine. Pairs of ocellaris and percs have even worked in rare occasions, although obviously not natural. Since they're both ocellaris, though, it should be ok.
