corns have got to be about the easiest snake. Especially being in the south, they don't require much heat. Mine all have one UTH each. 2 of mine are on papertowels .. with a hide each. All have bowls big enough to fully submerge in because they will. And all have branches to climb on. My last corn is in a bigger tank as she's over 4ft, and on aspen ..the smaller corns will be on aspen when they're bigger too. They all burrow, whether under the towels or aspen.
Some of my corns are not too squirmy. One is VERY calm and laid back when out, one is pretty squirmy and hissy but NEVER bites..just irritated with handling at all lol. The newest is a BIG corn and is squirmy for awhile but calms down.
