Need Help! Anemone not doing good.

[gcl581]

Ahhh!! Anemone is not doing good.

It’s a green bubble tip, got it on Saturday. It has been doing really good and even had a very small percula clown hosting it already.

When I came home from work, I noticed it looking pretty rough. His moth is wide open and the bubbles are all deflated. The Clown has also been biting the side of it.

Even though it looks dead, it is still attached to the rock and has no smells. the pics are from last night and just a few mins ago.

-AIO 10 gallon so its only about 8 gallons, Current _PC 80 watt.
-ph is 8.3
-salinity is 1.023
-temp is 26.3
-ammonia is untraceable
- nitrite is untraceable

thanks for any help
