Thinking of getting a cleaner animal to service my fish, either a bunch of cleaner shrimps or a cleaner goby. The goby seems to be a silly animal that is interesting to watch, but I'm not sure if predators will avoid eating the goby, as they do cleaner wrasses and shrimp. Primarily looking at eels, but also predatory wrasses and small basslets. If they won't work I'll settle for shrimp.
