Astraea snail chowing down on nuisance algae

This past year, I rediscovered how great an army of snails can be. At Tidal Gardens, we go pretty light on cleanup crews in general. For example, there really aren’t any hermit crabs to speak of in our systems. In 5,000 gallons of reef tanks, there may be only one or two hermit crabs. Most likely they arrived as refugees from local customers taking their tanks down who needed to re-home some of their inhabitants. I am not a fan of crabs because there is always a risk they might kill something they should not be killing, like another member of the cleanup crew or a coral. Long story short, I don’t trust them. I don’t have the same level of distrust for snails MORE
