ok now im scared with all this heat mat talk. i just got a new pacman cause my last one from petco decided not to eat, so i went and got a pretty big fantasy pacman from the LPS. and i have had a heat mat on my tank all the time. all i have for heat is the mat, one of the ones that sticks to the bottom of the tank, and the original bulb in the top of the 10 gallon aquarium. should i just unplug the mat heater? i have the substrate really deep, like 4", i didnt think it was going to expand as much as it did, so.... should i just unplug it?. thanks
