I'm just about ready to buy an anemone and was thinking the same question, my tank has been running for about 9 months now, tons of coraline algea, peramiters are stable, have shrooms and caps thriving well, my lighting consist of 2 175w 10k mh's and 2 actinic lights day and night effects, how about a Sebea anemone, and how hard would it be to keep? would I have to do anything to get my clowns to take to it?
