You really can't generalized. I always heard complaint of newer homes not built as strong as older homes. Some large development homes today are framed with synthetic paper material for outside walls, not plywood. If safety is the concern, all tanks should be placed in the basement as most fish rooms are. But a show tank is a living art that ought to be a center piece furniture in one's living area for appreciation, not to be hidden in the dirty basement. If you watch the "TANK" TV show, the show tank is always placed in the prominent living area of a wealthy home.
