I just put a UTH on Cee Cee and Selena's tank...figured I would try it out on them...I ordered another one that is coming for the albino...just have to be careful and keep a close eye on them right now as my thermostats haven't arrived yet. Cee Cee and Selena have decided they are in snake heaven...they have been lounging around over top of the heat mat since I turned it on...
