lol well i think u covered just about EVERY aspect of snake care! lol. my advice to you would be to read read read and when ur done that read a bit more. There is no end to the amount of reading and knowledge u can do with herps
but to give u a basic idea, it really depends on what your after, bigger snakes often require bigger attention. by this i mean bigger enclosures, bigger food, bigger equipment in general. Im a big fan of the
childreni group of snakes, they are a small breed and most dont get mroe then 4 ft full grown, this makes them great for someone your age as the tank doesnt have to be HUGE like it would with a
jungle etc.
wat i did was found one that sounded good (small, fairly placid, etc) then google imaged it, if i didnt ilke the look i kept looking, once i found one i liked (the
children's python) then i did lots of research on it. After u find the breed then its easier to look up what sort of equipment u will need for it. Hope this helps!
