Nice rack lol... Tommy is right, racks take up less room.. I have a 20 tub hatchling rack in the same spot that I had my shelf holding 2 20 gal tanks. i now have room to house 20 babies where as before, I had room for 6.. Not to mention, my beardie and his 40 gal breeder tank sits on top of the rack.. Build you own and make it the to fit the room you have available..
