oops

Generally when they get damaged they don't make it. I had one recently get on a power head and just got a small peice ripped, it was dead in two days even though the rest of it looked great.

 

They are a pretty touchy anemone, I would say its probably toast and would watch it pretty closely. Anemones are really hard to get to heal even in very stable, established tank setting.

 

i have also heard that there hard to heal.

 

I had one get sucked into a powerhead and it went over my overflow into the light deprived sump and it was A-OK in a few months with no special treatment. So don't give up hope all together!!!
