Well I woke up 30 mins ago and went and checked on my red tail and her tub is cold. thermometer says 67 degrees and it turns out the UTH (ive had for 2 years) I guess quit working. I tried everything and still no power to it SO i got it off right away. Now, I have a petsmart near me that sells an exo-terra UTH for $30 but the reviews aren't so hot.( apparently even when controlled with T-stat it only gets warm? Idk) I need to get her a heat source now though. Can this flexxwatt that everyone uses be purchased in a store? If so, where? Or is there a better place to find a UTH? I appreciate any info I get, as usual so thanks in advance.
