Green BTA issue?

[Boco]

So i went out of town for a little bit over the holidays but my parameters stayed stable. 1.026, 0 nitrite, 5 nitrate, 0 phosphate mag and calcium are on the high end of the scale, ph 8) the whole time i was gone. When i left it was full happy and healthy. I came back about 2 weeks ago and its been shriveled up but periodically seems to reinflate some then goes back. A few days ago it was stretching its self out but now its back to this.. its definitely alive and reactive... But curious if anyone has any thoughts on what i can do to get it back to normal. My other BTA is just fine and happy.. i appreciate any thoughts also the tank is about a year old.

Do you feed it?

Rarely, havent fed it in probably a month or more.

next time it stretches out, give it some brine shrimp or something. see if it reacts

There is still alot of color in the anemone, and im hesitant to try and feed it since its in a bit if a corner where i cant see very well to target feed safely. My camera was between the wall and the glass to take this picture.
