I looked all over the internet trying to figure out what these are. So thank you in advance for any response. First noticed them after live rock had been in tank for a few months. If you look at the pic you will see what looks like a bivalve shell with spines on one side. At first I thought it was a limpet but the ones I have move around. Hoping they aren't bad.

Could you post a pic with white light?

Yes yes..that pic was awful..it was a hard angle to get a good shot bc they are all clustered under one arc rock. Spent more time googling it again tonight.absolutely puzzled. They have a hole as well as what look like a typical bivalve mouth. Who know! I will post pic tomorrow a clear pic.
