Nidorina, then Nidoqueen (you'll need a Moon Stone)
A little girl in one of the underground paths will ask for a nidoran male if you give her one you will recieve a nidoran female.
u can trade a girl nidoran for a boy nidoran w/ a little girl sitting next to one of the underground tunnels.
nidoran female evolves into nidorina at 16. after that u need a moonstone to evolve into Nidoqueen. same story for nidoran male. 16 and then moonstone for nidoking
Nidoran (boy or girl) evolves on level 16. Boy- Nidorino nidorino w/ moonstone = Nidoking Girl- Nidorina nidorina w/ moonstone = Nidoqueen
Grimer, Koffing, Nidoran Boy and Girl and their evolution chain.
Neither- its entirely up to you! the best is the one which is trained the best
Yes, the female nidoran is blue and male nidoran is purple
you can find the nidoran male and frmale in the safari zone. You can also find the male nidoran in route 21.
Nidoran will evolve at lv 16
Nidoran evolves when he or she reaches level 16.
You can't get nidoran in emerald only in firered and leafgreen.
I'm assuming you want to know what level Nidoran evolves in Soul Silver. Nidoran (both male and female) evolve at level 16.
