Do kings really need under belly heat?

So I'm working on a new tank for my kingsnake and I've got the temperatures down on the tank but I don't have a UTH for said tank. On the tank I have for him now he's got all the bells and whistles I was just wondering. Because I'm working no money. But Don worry about the snake he is doing fine and has food for a long time

I don't have belly heat on my kings.

Really? So is it only needed if you need the heat? Thanks for not going off on the whole if you don't have money don't get a pet speech

No snake NEEDS belly heat. This is a myth. However you meet the temp and humidity requirements is up to you as long as they are met.
