Clowns are anything but funny sometimes. My maroon clown is now knocking down all the corals I have placed close to his anemone. I actually watch him haul off and head bunt it numerous times until it falls down. I t would probably knock him out cold if I glued it down
As if they are not silly enough, a knock to the head might retard them a little more.
My friend has a maroon clown and he is afraid of the fish. He bites really hard I guess. Mine still is a youngster so I have not had issues with him yet...
