Carpet anemone not doing well

[syncro]

Thanks for all the replies.

Today it is expelling wisps of brown fluid the consistency of syrup - partially digested food? Equivalent of vomit/diarrhea? It was doing this when I was feeding more heavily. It is still eating and foot has remained buried in the sand. However, not very sticky anymore and slower to respond to poking. This is a haddoni (no spots/stripes on the underside).

Ideas:
More food: Already tried up to the equivalent of a silverside every other day. Did not slow decline. Intuitively, the current behavior doesn't seem like under-feeding but it isn't a human.
Flow: Ok, moved the MP10 closer and one notch faster.
Irritation: There were bristle worms and brittle stars, so irritation was possible. Removed these along with RBTA yesterday.
Water quality: Possibly still have chemicals from RBTA. Possibly sick carpet is contaminating the water. Any other tests I can/should run?
Lighting too high: 250w MH on for 9 hrs, T5s on for 11 hrs. Too much light? Acclimated to this level over 9 days. Too fast?

Today:
- changed out the carbon
- 12% water change

I would up the flow to the point just below where the gravel will blow around.

The carpet anemone is doing better. Staying expanded during the day. Fast feeding response and is keeping the food down. I am feeding once per week about 2 grams. Still not very sticky and many of the tentacles are retracted. I think he is slowly recovering.

The carpet anemone is nearly fully recovered. Thanks for all the help.

I've just put the BTA back in the tank and the carpet is showing signs of stress. It appears they are not compatible. So either the carpet or the BTA has to go. Tough decision.
