Some revision to my original post is needed.
The tank isn't actually 80gallons, its about 75gallons with the dimensions of about 48"x18"x20" (lwh). Asking $140 OBO.
The 45gallon is actually a 50gallon with the dimensions of 36"x18"18". The metal stand is old school style, lifting the tank up above the ground about 1 feet high. Asking $150 OBO for both stand and tank. Stand and tank must be sold together. Stand would probably make for a nice coffee table

.
Pictures of the 45gallon should be available tomorrow night. Pictures of the 75 will probably be up by the end of the weekend.
