Perhaps I'm being a bit too cautious but I was looking at MarineDepotLive at mushrooms and a remark that they posted on their site got me thinking. It regards several mushrooms, i.e. zoanthids, and the powerful toxin that they release. They suggest gloves when handling which sounds like sage advise but I was left wondering how serious this stuff is. Does it transmit only upon touch or is this toxin 'floating' around the tank? They certainly are desirable and I'd like to have some eventually but I'm not quite sure what to think about it. How do you deal with it?
