Thanks Robbie!
My clowns have gotten into the bad habbit of ripping off all the tentacles around the mouth. Around the mouth, they seem to constantly rip off tents and let them go - why? not sure. They don't do that around the edge of the disk, but the center of the nem, they are really rough. They spawn like clockwork. The anemone seems to put up with it. Been doing that for a while now. When they lay, they bite the edge of the nem so it receeds. Maybe they have a mind set of biting tents no matter where (when they are getting ready to lay). But it's gone on for a while now. They are really, really rough.
