Hammer coral partially closed up.

I noticed last night that a few heads were closed on this hammer. I thought I would check it tomorrow and see if they are still closed. Well they are. I have not added anything to the tank in months. And this colony is over 2 years old. I noticed little brown specs on the flesh but can’t get a good id on what it is. Should I remove and dip it at this stage or give it another day.

anything change with lighting, flow or water chemistry recently? It's odd that only the top and center heads are closed up, makes me wonder if they're suddenly getting hit with more flow or light

Is it hosting your clownfish and they are bothering it ?

How is your hammer doing now?

The protrusions on the stalks are new polyps growing

Many of the closed heads are pinching indicating they will split soon. I notice my hammers and torches close up and / or don’t expand fully during the process

I had somehow had a change in flow. I shut off the one power head that was giving them flow for a few hours and they opened right back up.

Sense then I have done a complete tank over haul to remove a bunch of BTAs. Hammers and torches have never been happier.

That's great news! I love a positive outcome...
