Larger tank with under heat mat option.

My Hopper had become a big lady and I need to upgrade her enclosure. I would like to get a 5x2x2 at the very least. I'm having an extremely hard time finding an enclosure of that size with the ability to use an UTH. The ONLY reason I don't use lights is because she would not eat with the lights above.

Any advice would be amazing! TIA!
