hermit crabs arent cleaners. They will eat algae like off the rocks and stuff, good for cleaner crews, if thats what you mean by cleaners.
Cleaner Shrimp are cleaners, the ones that set up cleaning stations for the fish and clean the fish as they go by. The cleaner shrimp family includes:
Skunk Cleaner Shrimp
Fire or Blood Cleaner Shrimp(they look cool I have one)
Peppermint Shrimp
