Ok so what? Lol I'm confused.

Do I really need uvb? Can a basking bulb do it? If not what's a good daylight bulb for them. My room is dark so I need a daylight.

Also should I just jump into a 10gal for now? Eventually I'm getting an exoterra but what's good for now? One of those fish tank 10 gal is okay? Or just a critter carrier?
