ok, i have my bp in a 10 gallon tank with a 75 watt bulb, and a 8'x8' uth. the light i have 12h on and 12h off and the uth on 24/7. she usually active at night of course, and if i handle her even a little bit after ive turned off the light, she is quite cold to the touch, and lately she hasnt been moving around alot, it doesnt get below 70F at night (well MAYBE occasionally would dip down to 68F on a really bad night) but shes always got the uth right under her hide and ive put my hand there and its quite cozily warm, so im just worried if my temps are right at night, i know the 68 thing is pretty bad but ill try to let that never happen again.
