molluscs

Many people consider snails a pest, but in the reefkeeping world snails fill a vital role. I have many different species of snails in my aquarium, each of which has a different “job” with regard to cleaning up the reef. In combination, this slow but efficient “clean up crew” will eat almost every kind of detritus and algae. Unfortunately, they don’t always get along well with the other inhabitants of the tank. The seahorses mostly ignore the snails (except for the occasional harmless hitch on a passing shell) but I cannot say the same for the shrimp and crabs. Escargot
