I just got my 2 month pacman on the 5th. He/she has the coco substrate, a fake plant, fake log, a reptifogger for humidity, and a water bowl big enough for him/her to fit in. I live in Nevada so it is starting to get cold, a very dry cold. The temp in the tank is between 55 and 60 degrees, I know that is too cold. I am planning on purchasing the zoomed under tank heater since bulbs dry the tank out. I have read a lot about how to heat the tank and no one seems to agree where to put the heater. Should I put it under the tank (on the outside of course) or on the side? If I put it under I plan on only having it on one half of the tank so the frog can regulate it's temp. I just don't want to waste money if there is a better solution, and if I do get the zoomed under tank heater I want to know where to put it because it permanently binds to where ever I put it on the tank. Please help!
