Just watched a bit of the other video.
He is right about some things but not about others imo/ime. Like I agree there is a comparatively narrow optimal temperature range for these guys, but as far as not keeping them in racks because they don't like being shoved? Sounds silly to me, and contrary to what I have found. There is nothing wrong with proper caging, and yes even proper rack caging.
And this guy LOST several bloods just a couple years ago to URI from low temps? That seems extremely preventable...
And then he is surprised that the blood python takes to the branch when it is stressed from being handled and there is absolutely no cover on the ground. I don't find that surprising. No one said bloods can't climb. If there was substrate or a hide on the ground though, I think the blood would much rather retreat there than into the branch.
