wow, so sorry! I also have all of my tanks on gfci, but sometimes it's not enough to trip it, I guess.
I recall working in one of my tanks for a while....rearranging the driftwood and being picky about placement so I had my arm in and out of the tank for a good 10 or 15 minutes, I'd guess. I kept bumping my arm into the shoplight hanging over the tank and every now and then would get a very very small zing. I thought it was just the corner of the metal poking me in the arm....then it got strong enough one time for me to notice that it was more than just a pinch from the metal. I freaked out and blamed the light, but after thinking about it, realized that since it didn't zap me every time, It must be the heater switching on and off. I pulled the heater from behind the mattenfilter and yep....cracked. The fish didn't seem any worse for it.
