A week ago I got some new live rock that came from the Gulf. It had something that looked like a sponge that was dying. When I took it out of the bag, it felt like it had a shell. After it was in the tank for a day, it had a lot of soft stuff around it. I removed the mess and left what felt firm. My blenny and crabs have cleaned up the rest of the soft stuff. Today a hermit crab was crawling over it and it appeared to be loose and blowing in the current. I reached in and knocked the crab off and attempted to remove the object thinking it would easily come off. It was now stuck tight to the rock and has a firm shell. I didn't try to force it since it must be alive to be able to quickly stick to the rock.

I had another say it may be a turkey wing clam, but the shell doesn't feel as hard as a clam shell. In fact after I put it in the tank, it was soft. I didn't feel of it again until today and now it's firm, not hard.

Fleshy Limpet perhaps?

It's an Ark Clam. It feels softish because of the stuff on the outside of the shell.
