Would it be okay or more beneficial to place two under the tank heat mats inside a 20 gallon long tank?
I would place one on one end (for basking 90 degrees) and one on the opposite end (80-82 degrees). I would place her water bowl on top of the 80-82 degree heat mat. I figured this would help with humidity in a glass tank. I would also cover that portion of the mesh screen.
Experts please give me your two cents!
