Anyone have had cleaner shrimps bother or eat Acro polyps? One of the two I have likes to walk over and harass one specific Acropora (ORA Bellina), forcing the coral to retract polyps. The polyps comes back out after some time, but the shrimp does it again. I think it might be time for a time-out for this shrimp I've never had a cleaner bother SPS before ... only CBS bother LPS and soft corals.
