Forestal,
Did you post a similar question in the new/general forum? If so, your anemone is not a Heteractis (can't be, wrong ocean). It's the Condylactis anemone; either the Condylactis gigantea, passiflora, or florida--the giant purple-tipped anemone.
I replied to your post (if it was you) in the other forum with care information. Go to wetwebmedia for the definitive word on tropical west atlantic anemones & their care.
Regards,
