I agree w/ Roka. A carpet anemone needs more lighting that 220 watts of PC
lighting. It looks like it is losing color, likely bleaching out. I've always understood that one good way to test the health of carpet anemones is to touch them. A healthy one will be very sticky, so you will want to do that with a glove. If it's not holding on to food, I imagine it's not happy at all. I would consider some MH
lights soon, or start trying to feed it more often and get it to accpet some meaty foods. Sorry. Carpets, along with Ritteri anemones are 2 of the hardest anemones to keep, and sadly, the most common that die in aquariums.
