Here is my current set up. Substrate is eco earth/playsand and is 4.5″ at deep end. I have a large fresh water and saltwater pool with air stones. temp is around 80 degrees during the day cycle and 75 during the night cycle. humidity fluctuates between 70% and 90%, but generally around 80%.
This setup is lacking substrate depth, climbing area, hidey holes, air flow, temperature variations, and proper lighting. The goal of this build is to make a more “natural” environment, to increase activity and overall health of the occupants.
If you see any other inadequacies, please feel free to point them out.
