Goldeen is a white fish Pokémon with orange markings on its tail, back, and fins. It has a single fin going down its back, and thin pectoral fins. Goldeen's tail fin is admired by many for its beauty as it billows very much like a ballroom dress. It has a large horn on its forehead.
A male has a larger horn, while the female has a smaller horn.
Goldeen's large and dangerous horn is its main weapon. Although not known as an aggressive Pokémon, people swimming in waters that Goldeen are known to inhabit should be wary of being rammed.
Goldeen can be seen swimming upstream in large schools during the breeding season in spring. Goldeen swims at a steady speed of five knots. They love to frolic and dance in bodies of water and dislike being kept in captivity. A Goldeen in an aquarium will use its powerful horn to smash its way to freedom.
Goldeen are a very common sight in any body of fresh water like ponds, lakes, rivers. It can be fished up in Kanto and Johto.
This Pokémon was unavailable prior to Generation I.
