Eeerrr... umm I use a small reptile heating pad on the side of Dumper's (WTF) tank to get the temps up to the mid 80's. I was hoping it would get up to 90, but no luck. He's sleeping on it right now. So is this a problem? I've been using it for 3 weeks now.
edit: I pulled him off the glass opposite the heater and pissed him off... he kicked at me (he doesn't like to be woken up) I snagged a thermal camera from work and his heating pad rates at 100F. Dumper's skin registers at 80F. Is that too warm for him?
