wow, this is one thing i love about forums like this, seeing the differrent reactions to weather and stuff. Here in Florida, we are the Lightning capitol of the world, and i don't think twice about a thunderstorm. I mean, ive got surge protectors on all my plugs, and there has been an occasional time where i had to replace one. I think if you are really worried about your fish, get one of those strip surger protectors, that way if your house gets hit, it will trip and turn off before anything can hurt hte aquarium.
