the watts per gallon isnt really a good estimate, and you could keep a few low light softies, but no not most anemones, there are a few that dont have high light requirements, but generally they are from the caribbean and they are not clownfish hosts, if your going to do FOWLR then just do that, wait to do corals till you have some SW experience and if you are still interested in the hobby change your FOWLR to a reef,
