Working at a lfs I am amazed at how many people are surprised to learn about some of the things that could make you at the very least sick (and worse

) that we keep in our little eco-systems. Im hoping perhaps this thread could become a sticky and be used as a guide for new (and possibly old) hobbyists. People need to be aware of some of the hazards the we commonly keep.
I thought maybe other canreefers could add to the thread if they had a picture of the fish,invert, etc and provide a link to the pertinent information. In thinking about the list of potential "baddies", I realized I have only one thing in my tank at the moment that could "get" me. Not really comforting considering the one thing I have is probably the only thing that could potentially prove to be fatal.
Zoanthids.
A coral touted as being a good choice for beginners and both easy to keep and frag. While all this is true zoanthids contain a deadly substance called palytoxin
http://en.wikipedia.org/wiki/Palytoxin. Extreme caution should be used when handling your zoas.
-wear gloves
-if you cant wear gloves wash your hands thoroughly after
-do not handle your zoas without gloves if you have an open cut on your hands.
-while fragging your zoas, wear eye protection.
