Picture sucks, sorry. I thought this was a piece of dead coral. It was attached to a sponge when it came with my live rock. It fell off and I set it back on the rock the other day for no reason, and then I noticed it moved a few inches. I assumed a crab moved it. Then it had moved a few more inches, and last night it fell into the sand.
The white is hard and porous like a dead coral. There appear to be some "things" sticking out on one side now (it is not a hermit in a new home) that i did not notice before. The coral piece is shaped like an ear and is about the size of a quarter.
