The tank is a 40b, what size UTH should I get? I can get anything I need tomorrow. I really don't want to spend 50 bucks on a UTH and a thermostat. Is there any way around this? I can modify the hides so that they are alot tighter on him. I can afford to buy any UTH I need, but I can't really drop another 30 for a thermostat, being 14 and all lol.
