thats not true bobby. My are hosting a clam right now. They were hosting a large colony of zo's I moved that to a different tank and moved my clam to the place my zo's were. Now my clowns are hosting the clam. They have already layed eggs on the side. Papa stays at the bottom out side of the clam near the sand and mama stays about a half inch from the top of the mattle what makes me mad is that i have 2 RBTA inches a way from the clam and they wont even look at them.
