it's when my skin gets caught on the lip of the tank that hurts. I've broken the skin on that before jerking my arm away.
what kind of neolamps do you have?I got bite by one of my neolamps last week, the fish is about 2" and it actually drew blood, quite a bit for the size of the bite. Didn't overly hurt at the time, and wasnt until about 5 mins later that I realised it was bleeding.. but after 30 mins or so it stung pretty good.
