I keep short tails and bloods, but I do have one young ball python, and he is the biggest pain in the butt out of all of them.
That's so funny, my Borneo STP is my only pain in the butt eater in my crew. My BPs are both fantastic eaters.
Just goes to show, animals within the same species are still individuals and there are no "one size fits all" troubleshooting methods.
