BP Swimming?

Yeah, BPs swim fine. My hatchlings actually sometimes belly flop straight into their water bowl. They figure out swimming much faster than crawling. Though they scare me because I don't know if they understand they can't BREATHE underwater.

I generally only swim my bigger ball pythons when somebody's been rolling in a poo pile. Some of them kinda like it, and will hang out in the water blowing bubbles. Some of them really hate it, and will shoot out of the tub before they're even completely wet. And water temperature is a big deal---they really only like room temperature water, or just a little warmer. 75-80 degrees.

I bath mine when i noticed they havent pooped in a while but other then that i leave them be

Eh, only time I've ever had my BPs in the water is when they party all night long and are covered in feces the next day

If my BP's gets dirty etc... then i will put him in the bath but i will put something there in case he wants to get out of the water, like he will usually sit on top of a plastic container i put in the bath, but ye you don't really need to bathe them.
