Use caution when considering placing Limpet snails in reef aquariums that contain SPS corals as these snails have been known to sometimes graze on certain species of Acropora, Montipora and other similar species.
Rich not going to pull em but sure I could spare a few for ya.If they are keyhole I'd like a few if your getting rid of them. Few people I know have myrioma hydroids and keyholes eat them.
