Now that i have aquariums situated i was wondering about what to do in a 20L for my leopard gecko... I thought about a foreground and background but wasn't sure about the UTH getting through 3-4 inches of great stuff... then i thought of non-adheasive shelf-liner cuz that's very easily and commonly used with bearded dragons and uromastyx... but i wasn't sure if it would get too hot from the UTH and burn her... any suggestions?
