My snake (believed to be aged 6 months old) is in a 15 quart tub with holes drilled 1/2 inch apart and 1 inch deep coco bedding. (He hasn't eaten yet seeing as I've only had him for a few days). Anyway, his tub is warmed by a 1-5 gallon under tank heater by Zoo Med. The thermostat reads that the temperature is 73.7. The thermostat is set to 90. Is there is any way to warm up the tub using the same UTH or should I buy a new one. If so, which is the best?
