Goldfish Aquarium Care Guide

Keeping Goldfish in an aquarium requires the right conditions.

Aquarium Information

• Care level: beginner
• Temperament: peaceful
• Diet: omnivore
• Minimum tank size: 20 gallons for a single common goldfish, 30 gallons for fancy varieties, with an additional 10 gallons per extra fish.
• Compatibility: Generally compatible with other peaceful, cold-water fish of similar size that do not have a tendency to nip fins. Avoid tropical fish due to temperature differences. Best kept with other goldfish.
• Special requirements: Goldfish are messy eaters and produce a significant bioload, requiring robust filtration and regular water changes. They need ample swimming space and should not be kept in small bowls. A varied diet including high-quality flakes/pellets, live/frozen foods, and vegetables is essential. They are prone to swim bladder issues if fed improperly or if water quality is poor.
