A year ago, while I was cleaning a tank, there was some kind of "smoke" that came out of a rock when I moved it. I have no idea that was. Anyway, it was painfull.
It's hard for me to explain this in english. At first, it was just painfull but after 20 minutes, it was like my hand got scrubed on a hard surface. I immediately washed my hand but it did not stoped. The "scrubbing effect" of that smoke have last for about 20 minutes. I was a little worry let me tell you. That was weird and I would love to know what that was.

Urchins are another one to be careful with. http://saltaquarium.about.com/gi/dyn...2Ftopic158.htm

Again best handled with gloves.

This has been known to happen to many saltwater addicts

Perhaps the second most important hazard.

Don't forget Bristleworm Sting. I picked up a rock and the underside had a worm lodged in with its bristles out. Ended with about 500 little spines across three fingers. They swelled a bit and were sore but I could feel the effects for a month. Getting the spines out also were not easy.

I knew that some corals are toxic but I had NO idea that zoos were this toxic. I have never worn gloves and was not told I should by any other the LFS. I do and have had swollen glands on one side of my neck that the doctors are watching and the next step is more tests. Could this be from me handling EVERYTHING in my tank wo gloves? I did months of research before we got the tank but I guess I missed this tutorial!!
