LF-Anemone for my clowns

[GreenSpottedPuffer]

I am not really picky about what kind as long as it doesn't move around too much. I recently removed the coral that my clowns were hosting in and now I feel really bad because they hover at the front of the tank all day and night.

BTW, dual 400 watt metal halides, so light will not be an issue

Preferably green if possible. And in Vancouver of course.

Thanks!
