Gionopora not extending

[Dashiki]

I got a gionopora a couple weeks ago. I had an issue with my heater and the temp dropped from 79 to 71 overnight. Since then only some of the polyps will extend at a time and they only come out 1/4". Before it was closer to 2.5".

Anything I could do to fix/heal it?

Observe and try to get it to eat. Mine closes up sometimes on it's own for a day or two and comes back fine after that. I feed mine cyclops directly.
