even then youa re going to have to be realy careful, esspecialy with moroon clowns. make sure if you try, adding only one, and make it the smallest one you can find. Moroons are esspecialy hard to pair. some individuals will pair while others wont. Your best bet is to make sure your LFS accepts returns before trying and having a QT set up so if the female bashes the juvinile in too much, you can get him out. ALthough there will be a lot of violence to establish territory.
