As was mentioned, females take longer to grow into breeding age, so a lot of people start with a female~ just in case!!
The tank you have will be WAY TOO BIG for a baby ball python and will lead to stress and feeding issues. A 10g or 20g long is fine. In fact, it will always be too high and you will struggle with humidity issuesHere is a very good information sheet for setting up a glass tank: http://www.ball-pythons.net/forums/s...ad.php?t=56846. Remember that temps for a wee baby need to be around 92F and the cool side ought to be about 82F. Ambient temps need to be about 82F.
Lots of people use the Acurite thermometer/hygrometer to measure temps and humidity inside the cage and heat sources need to be controlled by a thermostat (Ranco, Johnson, Helix, Herpstat...) Uncontrolled heat sources get too hot and can cause thermal burns.
Bumping humidity by using damp sphagnum moss is a good idea. A bowl of it near the heat source ought to help a lotYou could also put some into each of the two hides.
