Damn! Give Ali a call at Amazing aquariums & reefs. He's always looking for cool nems. He actually spotted a mertens a couple of weeks ago when I was in there.
Little bit different. His is a gigantea anemone. I haven't seen a magnifica available locally in a while. I think PacificEastAquaculture has a few on their website right now. Just be ready to treat them if you do plan on getting them shipped as they ship poorly
