algea eating snails

[~chelle70~]

How many should I get? I have a 55 gal. The only cleaners I have is a cleaner shrimp and 3 hermit crabs (well, 2, one is missing.)
Thanks!!

you need a lot more crabs and snails. you can put up to 1 per gallon. If I were you, I would have prob 20 snails and 20 crabs and a bunch of extra empty shells for the hermits to move into as they get bigger.
