Is my anemone melting?

[Trooper182]

I've had this nem for over a month and it was doing great. Got back from vacation this week and noticed it closed up. Has stayed that way for a few days now. Decided to move it to a box to better monitor it. Also did the smell test and it doesn't smell like death. I don't want this to end up nuking my tank. Haven't had a chance to do a water test yet as I was planning to do it Saturday along with a water change. Also working on fixing some water parameters. Everything else is doing fine in the tank. The nem is host to two maroon clowns. What direction should I take with this? Tank is a 75g with two nicrew 150w lights. Water temp is kept 78F and 35ppt salinity.

It's definitely not happy. Usually when mine have gotten to this point they're not long for this world. I've yet to have one die and "nuke" my tank, though; typically they just continue to deteriorate and shrivel away.
