hello everyone, so this is what's going on. I have derasa clam it's about 7 inches wide, this clown fish has taken to hangout in it, in fact the clown hangs out in my open brain, my elegance coral and some big hairy mushrooms i have, yet it won't go near the RBTA I got for it !. is the clowns behavior dangerous to the clam ? if yes what do i do ?
