At work there is a rose tip anemone. The poor thing has been getting smaller and smaller. Its in a 15 gallon tank underneath a 48" (goes over 2 tanks) 4X54 watt light (2 actinic, 2 10K). The tank has an air stone in it and a sponge filter (also run by air). The water is 78*F. It gets a 5 gallon weekly water change using R/O water and Reef Crystals salt. It won't eat anything that I have tried (krill, silverslides, brine shrimp). It is attached to a small rock. Water parameters test good, specific gravity is 1.023. Is there anything I can do to help it?
