Gudgeon (fish)

Gudgeon (fish)

Gudgeon is a common name for a number of small freshwater fishes of the families Cyprinidae, Eleotridae or Ptereleotridae. Most gudgeons are elongate, bottom-dwelling fish, many of which live in rapids and other fast moving water.

Gudgeons in the family Cyprinidae

Various cyprinid gudgeons are found in lakes and rivers throughout Europe. Most commonly gudgeon refers to "Gobio gobio". This species is a rheophilic or schooling species that occurs in riverine habitats across continental Europe and the United Kingdom. "G. gobio" feeds on a variety of invertebrates.

Gudgeons in the family Eleotridae

Known commonly as gudgeons, many species in the family Eleotridae are also called sleeper gobies. Unlike gobies, Eleotridae gudgeons have paired ventral fins rather than a fused ventral fin [Helfman G., Collette B., & Facey D.: The Diversity of Fishes, Blackwell Publishing, p 264, 1997, ISBN 0-86542-256-7] . In Australia, gudgeons from the family Eleotridae are widespread and are popular aquarium residents.

Gudgeons in the family Ptereleotridae

Gudgeons in the family Ptereleotridae are primarily marine species and are often associated with tropical coral reefs.
