Much better to insulate the outside of a tank...and that's only to help retain warmth, it has NO effect on humidity. Humidity is affected by how much air flow there
is...ie. how much you cover the screen top. The plastic enclosures sold for snakes are only "better for retaining humidity" because there are only a few tiny gaps for
air flow.![]()
Covering the sides (even just with paper for now) to block the snake's view will help him settle in...he's just scared, his whole world just changed & it's confusing...
he feels threatened, don't take it personally. At least a week to settle in with no handling & no disruptions that aren't absolutely essential...as already mentioned.
And for any new snake, it's best to let them settle in to the point that they feed readily at least a couple of times before you interact with them...it's most important
that they eat.
