Euphillia specific issue.

[AdamK1]

What could affect fairly well just euphillia? My mixed reef is thriving, but my euphillia have been sulking a little recently. Not looking like dying, just a little reduced in extension, and pale.

I have acros, torches, zoas, Duncans, montis, a few softies... Everything else is looking better than ever, but the hammers are sulking.

Parameters are good, no visible signs of parasites. I threw in some flatworm exit to be sure, and bar 2 or 3 of the little purple type that I've seen from time to time that my wrasse don't get, nothing seemed to be floating about.

I did increase lighting by 10% recently, but the lps are all low on the tank, and nothing else seemed to mind.

Stable parameters. I'm not a numbers chaser, but all else seems well. Phosphate zeroed out a while back which I corrected, but this isn't uncommon in this tank, and I test and adjust weekly.

Any thoughts?

What type of Euphyllia do you have? Wall, Branching? What type of Corals do you have around your Hammers?
