How to Care for a Ball Python: The Complete Ball Python Care Guide for Beginners. In this video, we'll talk about how to care for a ball python. First, we’ll set up your python’s new home. Before delving deeper, some believe ball pythons prefer small, dark, plastic terrariums. This is false. Housing your ball python in an undersized terrarium may result in an overweight snake with underdeveloped muscles. Instead, purchase a terrarium that matches your pet’s size and provides room to move. Here’s an overview: 1, Hatchlings weighing up to 300g should be housed in an enclosure measuring 50cm by 28cm by 33cm or about 10 gallons. 2. Juvenile ball pythons less than 3 feet long require a terrarium approximately 90 cm long by 45 cm wide by 45 cm tall. 3. Adults over 3 feet long require a 120 x 60 x 60 cm terrarium.
