Vaporeon does not naturally appear in the wild in Pokémon FireRed, so you cannot catch them from the wild. However, you can obtain a vaporeon by using a Water Stone on an eevee.

Eevee can only evolve into Vaporeon with the use of a Water Stone, Jolteon with the use of a Thunder Stone or Flareon with the use of a Fire Stone in Pokémon FireRed and LeafGreen, it cannot evolve into Espeon or Umbreon because there are no day or night functions in FireRed or LeafGreen.
you cant just catch a vaporeon unless you Pokemon modify or cheat. the only way to get vaporeon is to get an eevee and use a water stone on it.
You must evolve the Eevee you get from Celadon City with a Waterstone.
