Can anyone please help me identify what these are!!!?????!! I've talked to a lot of experienced reefers, and no one can tell me what these are.. They never move, but they seem to be part of the rock.. I can't even get them off with tweezers.. They do seem to be alive, though, because they release a slime when bothered, just like coral!!
.. They are the red slug-like creatures on the top left corner of the rock..
