Although I have owned lizards, I am new to owning snakes. I am planning on getting a ball python in a month or two. The internet and a local pet shop have been invaluable in my research. However, there are some things that I cannot finds answers to so maybe you good folks can.

The pet shops in my area only use live prey. I would prefer using prekills. Can the snake easily adjust to prekills from using live? These snakes range from 5 months to a year according to the store. The smallest I've seen being about 12-15 inches long.

Also, if I start out with a 10 gallon tank, how long will it take for me to need to get a bigger tank? Or should I start with a 20 gallon?

And another, can 2 snakes easiliy be housed together? There are 3 or more in the pet store but those are young and I don't know enough about them as to how they share space as they grow.

I am sure I may have more later. Thanks.
