Hi, I recently purchased a normal ball python. I'm not exactly sure on the age, she is about 18 inches long. Is it ok to start her off in a 10 gallon tank at first and in about 3-4 months move her over to a 20L tank? I am worried that in the 20L she might feed a little vunerable with the extra floor space. and in the 10g I try to make it so she has plenty of space to hide.
