I have two cleaner shrimp. The red skunk kind... They have claimed a rock as their station to clean I guess. They have been in the tank for about a week now, maybe a few days longer. Anyway I have a Coral Beauty with a bit of Ich and now I think I can see a spot on my Metallic Fox Face! Anyway I have never seen these two shrimp clean anything except them self's! They will stroke the fish and they will all have loving pets and kisses but there never seems to be any actual work getting done. Whats the deal? Do they not all get along?
