Dragons4you.com its says you can double stack the tanks i was thinking of getting 2 42" x 21" x 14"H it says the fictures are in the tank so dont have to deal with annoying tank lights being on top has anyone order tanks from this site? The other site is npicages.com they have a 3 pack - 36" stackable cage 36L 19W 12.5T those are the dimensions of the tank has anyone bought from them? I dont really have a spending limit just want to hear feedback on ppl who bought from these site and if there satisfied with what they paid for or needed to buy additional things for the tanks
