I have 2 female babies living fine in a 25 gallon long zoomed front opening with heat mat and optional deep heat projector. No issues so far. I do have plenty of hides and feed them both well. Also I monitor them closely. Very closely
just letting you know sand can cause impactions which can kill almost any lizard and they live in rocky desserts not sand desserts, paper towels or coconut fiber is a much better alternative substrate that will not do any unnecessary harm to your pet
