Common Goldfish

The Common Goldfish (Carassius auratus) is a hardy, active freshwater fish. Originally bred from wild carp in ancient China, it is now one of the most widely kept and recognized ornamental fish species in the world.

Key Care Points:

• Behavior: Peaceful, social, and very active. Best kept in groups and suitable for both indoor aquariums and outdoor ponds.

• Tank Requirements: Requires strong filtration and frequent water changes in aquariums.

• Diet: Omnivorous; thrives on high-quality pellets, flakes, vegetables (like peas or spinach), and occasional live/frozen foods for variation.

• Lifespan: Can live 10–20+ years with proper care.

• Max Size: Grows up to 10–12 inches (25–30 cm) in large tanks or ponds.

• Growth Rate: Fast; can reach 4–6 inches in the first year under optimal conditions.

Mixed-color common goldfish are perfect for hobbyists who appreciate variety and motion in both ponds and spacious aquariums.
