Temp For Pacman Terranium

[countfrogula]

Hi All

So I have my pacman in a nice little terranium with substrate with a 40 watt light above during the day. it stays between 70 and 75 degrees night and day in the tank. I am told I want it around 85 by the pet store. Do I need to add a heating pad or is there any other way to bump temperature up 10 degrees? And should I put the pad on the side of the tank as I saw suggested in another thread? My frog burrows a lot I dont want him to get hurt.

Thanks all.

80s during the day for these guys is good, mid 70s at night. You can use a heat pad on the bottom but only cover a small area, and never place the heat pad below a pool of water.
