Someone jump in and tell me if I'm wrong, but Condy's are an Atlantic species, and most clowns come from the Pacific, right? So they are not usually together. I'm sure there are some people on here who have clown's hosting in them, though, because Lord knows they host in all sorts of strange things--even a plastic decorative anemone I read about on one thread!
As for the lights, it's probably a little weak. Again though, lots of people keep anemones under that type of lighting. IMO, I don't think it will grow or thrive as well as it would under more intense lighting--I'm getting ready to upgrade my own system for that very reason.
