Check alk and mag too. Low mag can make them mad.

It seems a little pinched in one area for some reason, but that can happen on occasion. If it comes back out, there is no issues. If it stays that way. If you have steady parms, then I would start looking for pests or something bothering it.

An astrea snail climbed on it last night could that have caused it?

.02 is a bit low for phosphates for Euphyllia. I would maybe try increasing feeding a bit.

As others have stated, you should also test alkalinity and magnesium (edited).

Did it respond to the food?

Yes it ate it, the tentacles closed in on the food, therefore it is reactive to the food

That’s encouraging, he’s still got energy to eat
How is he looking today? Getting an Alk reading will help. Also magnesium, many euphyllia thrive in high mag like 1400-1500. Send another pic! I’m rooting for this hammer!

I would say he's looking better already!
