Open brain / Surrey

[Trevis]

Hi there. I have an open brain coral that's pink and green on the inside. It's about 4" x 2". I've had it a few months now, was doing great until about 10 days ago. For some reason it's not inflating anymore, no skeleton showing but not inflating anymore and not extending its sweeper tentacles anymore.
I've been keeping a close eye on it for brown jelly or any other strange foreign stuff and there hasn't been any. Plus the rest of my corals are doing just fine.

Anyhow wondering if anyone wants to trade me something for it, someone who has a bit more knowledge than I do on the subject. I'm not picky what I get for it, wether it be a zoa/paly, acan/favia, etc. if you're interested please send me a message and we'll go from there. Thanks.
