School of Biological Sciences, University of Wales Swansea, SA2 8PP, Swansea, UK. "Seven different types of nematocyst are detailed and illustrated from the Zoanthidea"
I doubt the reaction was caused by the zoanthids though more likely there was a young bristle worm in the polpys and the OP got his thumb on one of them. but it is possile the op is sensitive and was in fact reacting to the sting of the zoanthids.

What I meant is they don't actively sting. Having nematocysts doesn't mean they actively sting.
“Cytotoxic Actions of Palytoxin on Aortic Smooth Muscle Cells in Culture”, The Journal of Applied Toxicology. “Intoxication by PTX leads to vasoconstriction, hemorrhage, ataxia, muscle weakness, ventricular fibrillation, pulmonary hypertension, ischemia and death.”
While zoanthids, like all cnidarians, do contain nematocysts or stinging cells, zoanthid stinging cells generally do not affect human skin.

It wasn't like a poke or a bee sting it was a tingling

but they do actively sting, evey time you touch one your getting stung. its just that zoanthid stinging cells arent powerful enough to cause a reaction except in sensitive people or maybe in open wounds, our armor (skin) is too tough for most case scenarios. I was basicly clarifying that they do sting and it is a possibility even though a remote one.

Man, I guess I really need to get specific today. You will not feel the sting of a common zoanthid by picking them up. Better? I'm using the word above as in to FEEL something, not whether or not they left behind an invisible something or other. I'm using the definition as in "sting: to prink painfully". You are using it as in "to pierce or wound with a poinsonous or irriating process". Does that make sense?
The "OW" you felt from while picking up your zoanthid, was not caused by the coral but something else on the coral. Zoanthids don't cause "OWs"

I guess, maybe you could clarify it some more though (just kidding)
I just wanted the poster to be aware of the fact that it is possible he/she is sensitive to zoa stings. even though its not generally a problem, and it was more likely a baby bristle worm or some thing like that.
how about this.
"zoanthid stings are generally not a problem for most people, though it is possible to be sensitive to them. its more likely another culprit is to blame for the sting"
work for you?

There are plenty of deadly, really cool looking critters in the sea. Not all of them are good pets.

I respect that there are many on this site that have a depth and breadth of experience that far exceeds mine, including some that have responded to this post.
However, when it comes to human safety, I feel the need to comment.
Zoas in fact can cause serious injury, and even death. I do not want to over-inflate the danger, but the reality exists.
It does not occur with all Zoas, and not everyone reacts the same, but it is also not limited to people with sensitive skin.
The potential is also not limited to zoas, although they are known to have some of the higher incidents of serious cases.
I personally know of three cases locally of nonhealing pruritic rash which fortunately were all treated and resolved.
Just because some/most of us do not have a reaction, we should still have a healthy respect for the life we keep in our tanks, and be careful when we provide guidance to others.
There are several articles on the subject. I will link one that discusses nonhealing pruritic rash.

i think the first time ever handled corals i used gloves, but time after that i just make sure i was my hand very well.
i usually try to do all my stuff which involves me putting my hand in the tank before my evening shower. havent got sick yet from the tank (that i know of) but, i ony have 2 corals lol, a hammer coral, wich i suppose is just like holding a piece of LR cos i hold it at the base, and a kenya tree, which i have fragged, and its a slimy git, but no illness, i think when i start fraggin more often i'll start wearing latex gloves, my mum owns a MASSIVE caring agency, so we have about 2000 boxes of latex gloves in my cellar:L

I dont think I ever once said sensitive skin. I just said sensitive, or sensitive people. or it is possible to be sensitive to the zoanthids....... I did not limit it to skin sensitivity.
thanks for posting about the pruritic rash, thats pretty cool information.

reefkprZ you are right you did not, but there was another poster who did.
However, I was not even targeting my comment to that poster.
I was making the statement because I have heard multiple times people blame any reactions on senstitive skin. (not in this thread per se)
Not looking to offend anyone, just hoping to help inform.

I bought my first trachyphyllia(sp?) last night and when I placed it in the tank my thumb got stung by something. It was burning last night, and is numb today where I got stung. I wonder if trachyphyllia is toxic at all?
