Hard to say with that light. It's not the intensity that's the problem, it's that it's too uniform. A really reliable way to encourage them to stay put is for them to basically believe that they are in the spot of highest light, and then they'll stay put rock solid. Otherwise it's a crapshoot, they might be easygoing but they might not and then they'll have wanderlust. It's a pretty common thing to see them rooted on the front glass, because guess where the most light and current are usually?

So .. sorry for the wishy washy answer but IMO it's a hard one to predict. It might be fine, it might not .. can't really tell until you try though.

As stated, they can and will get enormous, and they have the capacity to become very large very quickly in the right conditions. At about 24" around, I was not able to keep mine in a 90g, which is why I nowadays have a 30x30x30 cube, it was the smallest dimensioned tank I could fit the anemone into. I don't have the anemone anymore (sold it about 8 months ago) otherwise I'd show you a picture.

Anyhow good luck and if you could post a picture of it that would be awesome.

cheers
