So I've decided to get a python

Ive done alot of research and still have a couple questions.

alot of places say a 20 to 30 gallon tank is sufficient, but would it be ok to go bigger? I have a friend with a 55 gallon fish tank, would there be a problem with using that? (it been cleaned out, and i'll make a screen for the top)

Also, how do i find a good vet for my python?

and finally, I'm a student, so i'm generally gone during the day, will this be a problem?

also, any tips for the newbie snake owner would be very helpful!

Thanks!

BTW: I have a friend whose mother works with exotic animals, so shes trying to find me a mojave!
