I would put in a divider, light defuser (egg crate) works well. Most clowns are aggressive against other clowns. I'd think the true clown would terrorize the false, but that is a generalized statement.
My b/f had a "pair" that he got from our lfs wen we lived in OH and they eneded up killing each other. That was our last trip to that store, we choose a different store where the Owner sold him a mateed pair (his display pair) that were live caught together and they are very happy for over a year now. :mrgreen:
