I'm trying to identify this. It's on a piece of rock that I've had for a few months. I just noticed it because I moved this to another tank. It's on the bottom side of the rock which was laying on top of sand in its previous tank and is now exposed as you can see. It a lost looks to have a slit for a mouth like some kind of clam that doesn't have a shell. Never seen anything like it though. It's like a spongeclamslugcoralhybrid and it has a small piece starting to grow just below it as well
