So, reading the care sheet it suggests placing the UTH on one of the sides of the terrarium instead of the bottom. I've attached a picture of my baby albino pacman's terrarium (14L x 8D x 7H - roughly 5 gallon tank). Where would be the best place to put it, along the back or on one of the sides? Also, is a Zoo Med Repti Therm Mini (made for 1-5 gallon tanks) a good size to use?
