For context the bottom 2 hammers I’ve had for 6-8 months, the green hammer and the (dying hammer?) gold hammer I’ve had for a month or 2.
In the last week or so the top (golden) hammer has started retreating for an unknown reason. Parameters seem stable (all other corals are thriving) and there’s no sign of EFW or other parasites. Any idea what it could be?
My only guess is the emerald crab is perhaps nipping it at night!? I’m really lost to what it could be.
