Man...I love watching people's reactions at the idea of getting an anemone...
All anemone's do need good lighting - some more than others. Do some serious research about the different varieties of anemones, and what they are compatible with, care info, etc...
Lighting, however, is NOT the end all of anemone's. While important, feeding meaty foods is important too. Just do some research...
As for living in a DSB, unless you are talking about burying the thing in the sand, a DSB will only help your tank filtration and the anemone as well. Check on your lighting, and just make sure you have some rock, etc...for the thing to grab on to. You also want some current blowing around usually.
Water conditions must also be excellent.
