Sorry to hear it was so rough. This topic of zoa toxins is incredibly fascinating... it's such a common coral in the hobby, yet very few people have the misfortunate of getting it into their bloodstream system or into their mouth/eyes. But when it happens, it sounds absolutely awful.

Had a quick web browse... the section under 'Dangers' on wiki here:

a TFH article here:

The original scientific research paper cited by the TFH article:

Moore, R.E. and P.J. Scheuer. 1971. Palytoxin: A New Marine Toxin from a Coelenterate. Science: 172 (3982), 495-498.

I actually had some orange branching monti sting me the other day. One of my fish broke off a good sized piece, so I grabbed it out to frag it. It was obviously ****ed off and after cutting and gluing, my finger tips on my right hand were all tingly. Didn't hurt or anything, just washed my hand and all was good.
