Hatchling CAGE sizes

Would it be ok to house my new albino female ball python in a 10 gallon cage. Or should i go bigger, say, 20 gallons.

A ten gallon is more than large enough for a hatchling...make sure to have two hides a water dish and lots of folliage to take up all of that space. It may not seem like a lot of space to you, but to a hatchling python it is enormous. Congrats on the new snake and ask away with any questions you may have.
gosh, have been out of it for a while....make sure to supply adequate heat for your snake....a warm side of 90-92 and cool side of 80-82. You can do this with a UTh and a thermostat to keep your warm side constant. You can get a digital thermometer at walmart for around 12 dollars and this will give you an inside warm and ambient air temp along with your humidity.
