I suppose worst or best case scenario depending how one sees it, i will maybe have to rehome some or keep the same setup I have now. I have 3 90's one w the flower & con, one with the butti and a jewel, and one with 2 sals some catfish and tetras. I want to condense them down from 3 tanks to one larger tank for obvious reasons, but I am attached to all the fish I named for the new tank. The other ones I'm willing to let go. From my experience the con can hold its own with almost any tank mate and although I haven't tried the sal with lots of other large mates I've seen some aggression in one of them and from my research their reputation is that they are at least as tough as cons. I'm more worried about the two big fish not accepting each other and wondering how big I would have to go for them to live and let live.
