Looks like possibly keyhole Limpets

that's what it looks like to me too.... LA says this, although I don't take everything they state a clear fact...

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.

Man this and flatworms I feel like I was a dirty whore......... at least I can pick these out. the FW will need some medication.

I'm not sure they are keyhole limpets. There are several species of limpets, many are good grazers and do not harm sps. The species in my system does NO harm to anything.

The only harm they do is plug up float switches and anything else they can wedge themselves into.

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.
