I work at a LFS and I was pulling algae out of the 350g clown display, unaware that anemones could sting humans. I handle the small BTAs every day without a problem so I figured it didn’t effect people. I thought it was just the salt irritating my left arm because it’s not as conditioned to it as my right arm, so I left it there and continued to grab more algae for about another minute and then it really started to hurt. Thanks for reading, just thought I’d share this milestone lol.
