temperature gradient?

[ConcinusMan]

just to get an argument started, is there any need for further heat for garters kept indoors?

I say there most definitely is a need for supplemental heat assuming "room" temp is 68-72 F. It's important to have a gradient though so the snake can regulate it's temperature as it sees fit. Don't heat the entire tank. I know that most of the time my concinnus' preferred to warm themselves to the upper 80's. Cooler when in shed. A drop at night isn't critical but I find that especially for northwestern neonates, I have better luck keeping them eating/alive with nightly cooling. Nightly cooling also seems to increase daytime activity for all garters.
