A good source of info on bloods (and by extension the other short tail pythons, the care practices are VERY similar if not identical, size and some temperament/colors are the main differences I've seen mentioned by breeders elsewhere) is here:
https://www.bloodpythons.com/
They've got a lot of detail and good info, I recommend reading all of it closely. I'll highlight the most important bit below since a lot of care sheets on Google have this wrong from using bad sources themselves and is the #1 mistake people new to STPs make, even with a lot of other snake experience.
The key with short tails over other pythons is DO NOT use a lot of heat. They like temps in the 78-82 range, some like a 84 degree hot spot, others get cranky with that much heat. 82 is about the most they have to have to digest properly and doing higher heat, especially ambients, (85+) will generally get you the stereotypical "mean" temperament (wouldn't you be cranky if you were too hot?).
(2nd most common is keeping too wet or with sky high humidity. 60% day to day and 70% when you see a shed coming is plenty, they do not need nor do well with a swampy or wet substrate cage. Swampy cage generally causes scale rot on STPs)
I've had my blood about half a year now and he's been very good for me and quite calm.
