I have some tanks for sale and they are just the tanks, a couple 29 gallons for $30 each, a couple 30 gallons $30 each, a 34 gallon $30 and a 40 gallon $40 and a massive 126 gallon tank for $500 but willing to negotiate with the 126 tank and they all still hold water as far as I know, you must be able to pick up.
