I only have 2-3 inches of sand in the cages. I will add more and tweak the set-up when the breeding season comes along, in addition to lining the entire bottom and a few inches up the sides with plastic so I dont have to worry about the eggs adhering to the bottom.
The light colored specimen utilizing the ceramic log is a female, and she seems perfectly at ease sitting in this position all day. The other two in the squat 10 gallons are Matjaz-line and they, as well as the third male (an import from Africa) all have hide boxes and paper towel rolls as hides.
One of these days I may use the burrowing clay substrata or some deeper sand.
