Hey guys. I've been looking into pacman frogs, and I have a question about the temps. The care sheet on this site says that they should be kept at 80-85 during the day and lower at night, but the breeder joshsfrogs.com says the following: "It is widely circulated that Pac-Man frogs need temperatures in the 75 to 85 degree Fahrenheit range. While this is true of their natural environment, Pac-Man frogs spend the majority of their time buried in the cool ground. In captive environments the substrate doesn’t provide the same protection due to lack of depth and the ability for air to move under the tank. Therefore, normal room temperatures of 65 to 85 degrees are recommended."

Which of these is correct? If they do require extra heating I'm going to opt out of getting one, as I'd rather just get another snake if I had to dish out the money for a thermostat.
