+1 and no that anemone is not good..... :-/ first if you wanted to house a anemone , you should have VERY VERY STRONG LIGHTING! Then wait about 8 months to a year...... just to make sure your tank is established, and doesn't go thru ph,nitrates,ammonia,nitrite SWINGS that will kill it.......please do more reading as they have lots of interesting web sites on anemone.
But to answer your question: watts per gallon really can't apply much since lighting has advanced.
For a anemone I say go with any
4xbulb t5 high output.
Or metal halide.. And if you have mucho money LEDs will do.
