What size/type uth would you use for a 20gallon long tank.

Hey guys. I'm moving Hades into a 20 gallon long tank that I got from a friend. I was just wondering what type of under tank heater you guys would recommend and what size, either the 10-20 gallon size or the 20-30 gallon size.

It is best to pick a size of Under Tank Heater or Flexwatt that will cover between 1/3 and 1/2 of the floorspace of the tank. As far as what type of UTH, I like the Exo-Terra Desert and Ultratherm.
