I have no idea what they are. They seem to like colt coral. I think they may eat the coral, just can't tell and this is my first coral. They came with. LFS thought it was just a molt hanging on.
It was alive when I put it in the tank, then found a second one in the coral. This piece of coral is smaller than peanut with shell. Small one is penny sized overall.
click picture, the one I see looks really bad (edit)
