Which reptical is it? Vitamins or Calcium? Should be phospherous free and WITH D3.
A small bottle cap with some calcium to free lick when they feel the need is a good practice.
Here is my current setup:
Warm side humid hide filled with either damp eco-earth or spag moss. UTH + Infrared bulb on warm side. Plenty of warm and cool hiding areas. Slate. Water dish and feeding dish.
