Tank weight

[Mattyb]

So here's my question. I'm looking at upgrading my tank from 60 gal to 110gallon.my tank runs along the floor joists and not perpendicular to my joists. Do you think it's relatively safe being a longer tank (72). Everyone says it's too heavy to put that way otherwise it will fall through the floor. I've scoured the internet and not once could I find a story about a tank falling through. I wish mythbusters was still on because it would be a good episode lol. Anyone have there tank running parallel to the tank? Did you have issues? Any damage to your home? Advice would be much appreciated. Thanks
