Hmm, yeah I thought the toxins were supposed to take affect a lot faster. It could just be plain old anxiety but it never hurts to get checked out. Take it from someone who knows, sometimes the brain can play tricks on you and manifest some symptoms just because you are thinking about them.
A few months ago someone posted the article about the zoanthid toxins. For about a week each time I took my hand out of the tank I got anxious and felt just not right. It took me a while to realize that I was just worry about the toxins.
