I'm thinking that two of the 32 watt bulbs will be the least you can get by with. I don't know a whole lot about anemones. I do know that they, like many other creatures we keep in SW
tanks, are photosynthetic and will die without proper lights. There may be a couple that are not, but the majority are I believe. Anemones are really best left alone until you have gained SW
experience and have a mature tank for them. There are a few other critters you can keep in the low light. Mushrooms should do great. You could put some zoanthids in but I think they would need to be close to the top. Most kinds of star polyps seem to tolerate low light very well.
