green carpet anemone 1 ft radius
 

Has anyone ever heard of this type of anemone causing hives and swelling in humans?I've heard this type is poisonous but is that entirely true?

Not poisonous, no.....but they can sting you. When in contact with the anemone, it will just seem like the tentacles are sticking to you. After contact, you may develop a stinging sensation in the area it touched.

I had haddoni for a number of years and noticed that I would have really itchy welts on my fingers the day after contact. Not unlike mosquito bites or similar. Very itchy for about a day.

It is possible to have an allergic reaction to the nematocysts. .. it's better to use gloves if you have to handle them or working in a way such that occasional contact is possible. Just some of those disposable latex or whatever gloves are fine, the kind you buy 100 for $4 at Home Depot, sort of thing..

When Big Als was still open down south one of the girls showed me her arm after contact with a carpet. Her entire arm was starting to swell.
I think it's like a bee sting to humans. Some people don't react and some have to run for the Epi pen.

my g/f is the same way with bee stings. get stung epi pen comes out or it may not look too good for her. now i have a bluelined foxface so shes kinda keeping her hands out of the tank..

I've handled lots of anemones, and none of them bother me. My Bubble coral bothers me a little bit, just itchy skin for a couple hours though. Bloodworms though...can't be anywhere near 'em!!!

i had my anenome stuck to my hand, had to peel of each tentical. didn't affect me at all

I had a green carpet as well ( beautiful but nasty ) you can learn not to let them grab a hold of you by only touching the body. Mine once wrapped all up my arm and it took me a couple minutes to get it all off I was left with some itchy red dots but no swelling. I eventualy returned it to the store after it had destroyed my setup and had eaten about $200 of fish.
