From Bulbapedia, the community-driven Pokémon encyclopedia.
This is the Bulbapedia walkthrough for Pokémon Yellow.
These pages follow the original Game Boy iteration, not Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!. The guide for those games can be found here.

Route 4 (West)
The Magikarp Salesman
A Pokémon Center stands near the entrance to Mt. Moon. Inside, a shady man offers to sell you a Magikarp for $500. The fish is nearly useless until it evolves into the powerful Gyarados at level 20. With enough money to spare, you can end up with a strong Water-type Pokémon sooner than normal, but you can soon hook a Magikarp for free with the right fishing rod.
