-No physical signs of pregnancy.

The female was kept in a 35Lx25Wx20H (cm) plastic tub with plenty of ventilation on top and sides. 2 cm of coconut fibre on the bottom for retaining humidity and a thin layer of bark on top. 8 cm diam. water bowl in the middle.
There was no hide in the enclosure.
The tub was at room temperature (20-24 celsius) with a 20x20cm area of the side covered with a heatpad.

Husbandry for the young:
The 2i young were housed individually in 10cm diameter (250ml) delicups with 15-20 mm coconut fibre as substrate.
The young are fed 2 times a week with appropriately sized (headcrushed) mealworms, when the sides of the cups and the substrate are moistened with 5 cc of water.
