So tonight when the new shrimp hit the tank Butters immediately swam over to them nudging them and rubbing up against their feelers as if his shrimp was not only back but had duplicated into two.
My cleaner used to hitch a ride on the tang (no name, sorry), round and round the tank, cleaning him all the way. One of the coolest things I've ever seen.
Then tang went on attack mode and chomped his feelers, and the shrimp was constantly fleeing and eventually disappeared. Now the fish are confused because their cleaner is gone, so they harrass the coral banded to death. The CB tries so hard to be intimidating, but the fish just park right in front of him, waiting for a cleaning.
