Missed this one. My dad works for a fire and flood restoration company. He was telling me about how one time a really large and expensive reef aquarium started a fire. I think the stand caught fire and the tank crashed into the ground or something. It basically self-destructed and now there is no more reef. This wasn't some 2 thousand dollar deal either, this was a BIG tank. The water put out the fire, so there was just a small amount of damage to the actual home.
