I understand that cleaner shrimp clean/eat ick protozoans off the body of fish. Do they eat the protozoans that end up on live rock or a sand bed? If so, would not an aquarium well stocked in cleaner shrimp be a definite preventative against ick?
They definately eat them but that parasite is Soooo prolific I don't believe Shrimp make much of a dent in the population. I do think it makes the fish feel better and puts them more at ease.
