What’s this guys problem ?

[TwelveL16]

Hammer coral, I’ve tried moving him around but for about 3 weeks now he’s barely been extending. The toadstool is obviously mad too but fairly certain something is eating him. I think an emerald crab.

Any ideas? I’ve got another hammer in there who’s happy as a clam.

Alk 9-10
Calc 440
Mg 1440
Phos .046
Nitrate 20

I’ve had emerald crabs bother my hammers. I’ve stopped using emeralds as a result. Whats it getting for flow?

I’ve considered flow, I’ve tried him in multiple flow areas.
