I just noticed this growing in my tank and I have no idea what it is. Is it harmful?

In my experience the best way to deal with a bad coral is to gently smack it on the nose with a rolled newspaper.... But really it looks like some sort of zoa/paly coral. They are perfectly reef safe friendly corals that (if taken care of)will propagate smaller babies. |

They may contain a poison that can kill you. Research palytoxin to be sure you know what this is all about. ------------- 150 gal reef with 50 gal sump. Reef Octopus DCS-200 Skimmer. AI Sol Blues. |

The only time I've encountered palytoxin was in Palythoa grandis. Those are a Paly/protopalythoa (not exact on that one) I really wouldn't be worried about it harming you or anything in your tank.

In my opinion there is no such thing as a bad coral. Rather, there are some animals, Majano Anemone for instance, that we avoid because they have a tendency to take over an entire rock structure and push out our favorite coral. Coral and Anemone have nematocysts that sting in defense and to capture food. The sting and juices of some coral and reef invertebrates may, in rare instances, cause humans temporary discomfort and illness, but that is all. As someone who has been farming coral and getting stung by nematocysts for 20 years, I would enjoy those coral polyps. Blue Zoanthids and Palythoa are not that common. You have a cool thing there.

They can actually look quite colorful, green with pink tips. Years ago, before we knew how troublesome these were, I sold a rock of "Tulip Anemones" to a friend. To this day he still loves to tease me about it.  Pic courtesy of ultimatereef.net

I have found some species of the Palythoa genus to be prolific to a fault. They can multiply quickly and cover rocks. While they definitely aren't harmful, if you don't like the look of them now is the time to remove them. I've heard of these fabled tulip anemones.

| I was super excited when I found my first tulip anemone in my tank. It took me over a month before I realized it wasn't a good thing. |
