Keeping Western Mosquitofish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: beginner
  • Temperament: semi-aggressive
  • Diet: omnivore
  • Minimum tank size: 10 gallons
  • Compatibility: Can be kept with other robust, fast-moving fish of similar size. Avoid keeping with slow-moving or long-finned species as they may nip fins. Best kept in species-specific tanks or with other livebearers.
  • Special requirements: Requires good filtration and regular water changes. Can be prone to fin nipping, especially if not given enough space or if kept with unsuitable tank mates. They are prolific breeders, so be prepared for rapid population growth if males and females are present.
