Paly Problem!

Palys not doing well

I’ve had these palys in my tank for about a month and a half now which were thriving, however in the last week they’ve started shrinking and closing up (see picture) . Not sure what’s going on as all other corals in the tank are completely fine and have been growing great (see the paly grandis in background) it still looks like it has new growth (on left for example) so surely can’t be doing that badly!

Any ideas what might be happening?

Could just be taking a break - they do that sometimes.

Maybe try moving them up just a little higher, they kind of look like they are stretching.
