How would he get an RI when i have the top covered, and having a 110 with multiple hides is just a large scale 20 with one or two hides. The only reason i can see downgrading is because it'll be tough to heat in the winter. I might put him in the twenty for a while to see how he reacts, but changing environments is like the most stressful thing so idk how much ense that makes. idk, when i had my old snake in a ten gallon he would just sit in his hide all day, and at night he would just go back n forth, and see the same over n over, atleast now in the 110 the snake can pick from a variety of hides, climbs, heat levels, and generalized humidity.
