not totally it doesn't a 6 foot aquarium sits across the same amont of floor joists, the water bed has a bigger footprint sure but it also dispurses its loads across the same joists as the narrower tank, sure its may seem like is is being dispursed but the joists are still holing the same weight as well as the bearing walls. with a fish tank it can be placed closer to that wall making less flex in the floor then a wider water bed
