I purchased a few soft corals, and the seller tossed in a free frag of Galaxea, which, I have come to find out, has sweeping tentacles. Will I be stung if I put my hand in the tank and come into contact with a tentacle? Perhaps most importantly, does Galaxea contain palytoxin? I'm not sure whether I should be taking special precautions in this case. I was caught off guard by the free gift in my goodie bag of corals. Thanks!
