Hey, I got a question. I'm getting a female ball python and I do not want to put her with my male. (I don't want them to breed/ also keeping 2 together causes stress). So I'm buying her a 20 gallon snake kit from zoo med. as far as lighting/heating goes, it only comes with a deep dome blue day lamp and a heating pad, what UVB amount should I buy for this 20 gal?
