I disagree, halides are not the only way.
my flower anemone thrives under 80 watts PC. tube anemones dont even need light, just lots of food.
and then the almighty debate on if T5's are better or worse than halides, and in alot of cases, T5's can be.
BTA can be kept under PC, T5, and halides. i dont wana say VHO because i just dont like them, never did..
but i would leave the carpet anemones for the much more intense light of halides or T5's with proper individual reflectors.
looking for reef safe? flower anemones, BTA, and a few others may qualify. though ANY anemone can become a problem if it decides to walk, which can be triggered by poor water movement, poor light, poor water quality and whatever else the anemone might not like. many of the pro's argue that no anemone is reef safe, but actually just a disaster waiting to happen (such as a 10 inch carpet anemone walking 30 inches to the left, leaving a path of dead corals.).
