I'm designing a new viv myself, and I'm trying to figure out if I should go with an UTH and a heat lamp, or just the UTH. I'm leaning toward the UTH only because it will be a wood enclosure and it's going to have a solid top if I go that way. I'm planning on LED lighting, and I'd rather not have to make a screen covered hole in the top.Rexracer, I have a large UTH in the middle of the tank so it covers both setups and heat lights for both sides as well.
I do have to ask though, you only have a catch at the top of each door.
I know from working with acrylic that is is flexible so surely an average sized corn is strong enough to push against the bottom of the door and flex it enough to escape.
