That's a kind of anemone from cold/temperate water. Usually I wouldn't expect them to do well in a tropical reef setup but WWM suggests [possibly] otherwise.
Personally, I wouldn't mix and match temperate/tropical but that decision is ultimately your call. Here is the link I found:

Let us know what you decide. Maybe a full-blown coldwater system is in your future:P.
