I have a 20G IM tank that has about 16 rock flower anemones. They are about 4 months to a year old. Recently 4 of them went from nice colors to all green with brown centers. Is this common? I cannot remember changing anything in my routine: weekly 10% h20 changes, led lighting, skimmer, ato, SG-1.026, all parameters in range. I have 2 clownfish in the tank and I feed them mysis or brine shrimp. The rock flowers get nothing except possible fish food which drifts their way. Some of the RFA's are common and some are Ultras.
