Hammer closed today

[JBenton]

Still new to corals but my hammer is closed today, do these look like something is growing around the heads.

Could you please try to get pictures under white light? I think I see tissue recession but the pictures are way to dark to tell for sure.

I agree, the hammer appears to be receding. Can you post more tank info?

I think I found the culprit! The Peppermint shrimp I added to help with some small aptasia I thought were growing on a few frags I purchased aptasia is gone at least what I thought was aptasia anyway. But now one of the shrimp has been getting on the hammer and I assume eating at it.
