as someone who has tried to keep anenomes and corals under pc's, i'll just say this:
wattage per gallon is not a good way to determine what you can keep. they are decent in say a biocube or something, but pc's just don't give the PAR (strength) of light needed for corals/anenomes. heck, my zoos didn't grow under pc's. someone told me that if a coral isn't growing, it's dying. since ive gone to t5's, i understand what he told me. my coral growth has multiplied 100fold.
you seem to keep getting anenomes... how many tanks are you keeping these in?
i did though keep a bubble tip under pc's, and it was at the very very top of the tank. 3 months after i traded it to someone with MH, it was 5 times as big as when i gave it to him.
