Cannot id this coral

[cnl83]

I hope I am posting in the proper forum. If not, I do apologize.

I have this hard coral that came with my live rock. Im not sure what it is or how to care for it. Does anyone know what this is?

It is hard, that is all I know.

It looks like a retracted Duncan colony (Duncanopsammia axifuga) or maybe Tubastraea, also retracted

Hey WELCOME aboard Reef frontiers, what else do you have and tell us about your set-up

unfortunately i'm with TJL but that looks like its either very close or already dead. I can't really see any tissue where there should be at all..

Ok what about this? Its some sort of Clam. The only reason im asking is because Id like to try and keep it alive.

The first pic you posted looks like how my zoas do when they are retracted, but I'd say Duncan colony is the closest accurate identification. How long has the liverock been in the tank?

A week or so.

CNL83: The video you posted appears to be some sort of oyster or muscle. That and fantastic soundtrack, not often does someone pick lacuna coil.
