i'm no authority, but i think most will agree, for anemones and stonies of any type, you should have metal halide. a 2' deep tank would be fine with dual 250w bulbs.
please remember that anemones are a tough animal to keep. they are the one reason i got into this hobby, and i now know i will not have one for a very long time. i am going to wait until i am far more comfortable with marine aquaria, and i think most would recommend you do the same
in this hobby, i've found that patience makes perfect, and rushing will be your ruin (good grief that was cheesy, but you get the picture).
