Hatian anemones are Condylactis sp. They are an atlantic species and are known to be one of the more aggressive anemones, maybe that means their sting is more potent, or they just have more. Although all anemones should be considered fish eaters some have a worse reputation than others, the carpet anemone for one, and the Condylactis too. It is not a natural host for any anemone fish, and although there are cases where they have hosted them before, its not common. They have very long tenticals and a veracious appetite. Should a fish wander too close its very likely that it will capitalize on the opportunity. I have personally lost 2 clowns to one in the past. I replaced it with a RBTA and havent had a problem since.
