You must have a national dex and poke radar
go to route 201 and use poke radar
and that's how to catch nidoran boy or girl
hope i helped u.....
Both male and female are on Route 4
Try looking on the route west of viridian city.
NIDORAN evolves into NIDORINO and it evolves into NIDOKING. It is a great Pokemon infact i am training one, good luck.
Goldeen/Seaking, Nidoran/Nidorino, Nidoran/Nidorina and Rhyhorn/Rhydon learn it.
Nidoran Female and Male both evolve at Level 16.
Go to White Forest when Ken is the resident, if he is, use Entralink to go to Black City from Pokemon Black and you'll receive Nidoran.
At The Pokemon Safari In Fuschia City
Nidoran Male and Female can be found in these places: The route west of viridian city and the safari zone.
You can find Nidoran in route 3 (sometimes even Nidorino\Nidorina) and the Safari Zone in Fuchia city.
it appers on route 201 (mass out break)
Use Pokerader on route 201
Both male and female are on Route 4
You go to White Forest when Ken is the resident, then use Entralink to Pokemon Black and go to Black City, then he should be there to give it to you.
