So I am starting to get a good amount of green hair algae and I'd like to get it under control quickly. I have 2 red legged hermits and a nassarius snail but neither really care for the algae, so I was looking into getting an emerald crab but I hear if they run low on algae they will attack my hermits and snails so what I am getting at is, are there any other good algae eaters that I can get that will be safe towards my other tank inhabitants??
