Above are some of the suggestions on how to help your anemone recover. Other than the fact that it is bleached, it looks ok. you may want to feed it a little frozen mysis as you feed your fish tank. Dont feed it daily, once a week or every few days should suffice. Also, what brand of lights do you have? we need specifics. even though it is bright to your eye, it may not produce enough Photosyntheticly Active Radiation (PAR) to properly provide the liht needed for photosynthesis. the Anemone you have uses this to generate energy from the various algaes within its body. again, I woudl adjust your photo period to the 10 hour range and then watch it for a few weeks.
