thanks for all the replies, I mite have to remove the smaller one. I dont think there is a big enough difference in size, and that mite mean they are both females

. They have those little guppy traps at wal-mart(you know the ones you put the female in when she gives birth so they dont get eaten by the other fish) and see if the fighting will stop, but I dont think they will. The bigger one will hold its ground against anything in the tank. It never backs down, just puffs up and then goes about her way. Maybe my local store mite take the new one back for exchange for a really small one even though I didnt buy it there. When I got my first clown it was boss of the stock tank, that is why I got it( as well as the cool dark color). It almost looks like one of those hybrid maroons/purculas, but has the spikes in the fin. I hope im not to late, the little one is doing the seizure thing but no difference in the big one

. Well thanks again,
birchell
