Thanks in advance!
Ball pythons will max out at anywhere from 3 to 5 feet (1 to 1.52 meters) and from 1,200 to 3,000 grams. Exceptionally large specimens can be bigger.
I don't think even fish can be determined to grow depending on aquarium size. I believe that's a stupid myth based off of petri dishes and cell growth. If anything, your ball python may become a reluctant eater(therefor smaller) if you keep her in a huge terrarium and not provide her with a comfortable living space. To determine what is adequate housing, we must know how your viv is set up, but a proper setup contains two hiding spots, sufficient heating and temperature gradient, appropriate substrate, and a source of water. Food must be provided at appropriate times, which is about once a week, give or take a few days.
