My Cleaner Shrimp has Hung its Shingle

My cleaner shrimp is now hanging out in a particular corner of the tank. The fish somehow know he performs a cleaner service. The shrimp makes a meal out of parasites that live on the fish. The fish get the benefit of having the parasites removed. A true symbiotic relationship. I have seen my Royal Gramma, at least one Green Chromis and one Clown stop in for a cleaning. This evening he was doing a lot of business so I had my camera at the ready. The Royal Gramma does have one or two white spots on it. He turned out to be a repeat customer.
