Goldfish are among the most beloved pet fish in the world, known for their vibrant colors, graceful movements, and adaptability. Whether you’re a beginner or a seasoned aquarist, understanding the specific needs of these fish is key to keeping them healthy and thriving. In this article, we’ll explore three popular types of goldfish—common goldfish, fantails, and orandas—and provide essential tips for their care in tanks or ponds.
Types of Common Goldfish
1. Common Goldfish
The classic goldfish is hardy, simple in appearance, and perfect for beginners. They are sleek with single tails and can grow up to 12 inches in the right conditions. Common goldfish are best suited for ponds or large tanks where they have ample space to swim freely.
2. Fantail Goldfish
Fantails are a fancy variety with a rounded body and a double tail, giving them an elegant appearance. They are slightly less hardy than common goldfish but thrive in well-maintained aquariums. Their unique shape makes them slower swimmers, so they do well in tanks without fast-moving tankmates.
3. Oranda Goldfish
Orandas are among the most distinctive goldfish, recognized for their “wen” or hood that covers their head. This feature makes them a favorite for enthusiasts. However, the wen requires careful attention as it can be prone to infections. Orandas are best kept by experienced fishkeepers in tanks designed for fancy goldfish.
Setting Up the Perfect Habitat
Tanks for Goldfish
- Size: A single goldfish needs a minimum of 20 gallons, with an additional 10 gallons per fish.
- Filtration: Use a high-quality filter to manage the waste goldfish produce.
- Decorations: Avoid sharp objects that could harm their fins. Use smooth rocks and live plants like anubias or java fern.
Goldfish Ponds
- Space: Ponds should be spacious to accommodate the growth of common goldfish.
- Environment: Provide shade and vegetation to mimic their natural habitat.
- Water Quality: Regularly check ammonia, nitrite, and pH levels to ensure a healthy environment.
Common Goldfish Diet and Feeding
Goldfish are omnivores and enjoy a varied diet:
- Staple Foods: High-quality goldfish pellets or flakes.
- Treats: Blanched vegetables like spinach and peas, live food like brine shrimp, or freeze-dried options.
- Feeding Tips: Feed small portions 1–2 times daily to prevent overfeeding, which can lead to health issues.

Common Goldfish in Tanks vs. Ponds
Goldfish are versatile and thrive in both tanks and ponds. However, the choice depends on their type and your resources.
- Tanks: Ideal for fancy varieties like fantails and orandas. Easier to control temperature and water conditions.
- Ponds: Best for common goldfish, providing more space and a natural environment for growth.
