Sorry to say, but in my opinion, you do not have the lighting to keep an anemone. You have about 1.8 w/gal. Most anemones need higher intensity light to survive. Clowns don't need an anemone(even though they are cool together).
Beanie, pretty much 100% of anemones are going to meet an early death in aquariums........yes 100%. It's actually irresponsible for any of us to keep them, but more so in improper lighting. It takes months and months to kill them with bad lighting. I highly doubt they are "fine"......show pics. No flame, just telling the truth. Anemones will die. I believe you are new to the hobby right? if not, then sorry. The thing is when folks start, they don't really care what dies, but as you learn more and more and more about the hobby.....there comes a time when you simply start respecting these creatures much more. Don't ask "what are the minimum conditons needed".......ask "what are the right conditions".
