   • Scientific name: Carassius auratus
   • Common name: Black Comet Goldfish
   • Family: Cyprinidae

   • Adult length: Up to 30 cm, but commonly around 15-20 cm in captivity
   • Lifespan: 10 to 20 years, with proper care can live longer

2. Tank Setup:

   • Black Comet Goldfish require a spacious tank with at least 40 liters per fish to thrive.
   • Provide ample swimming space and consider the potential adult size when selecting the tank.
   • Include hardy plants and decorations, but avoid sharp objects that could injure their delicate fins.

3. Water Parameters:

   • Maintain water temperature between 18 to 22°C (64 to 72°F).
   • They tolerate a pH range of 6.0 to 8.0, but stability is crucial for their health.

4. Filtration and Water Flow:

   • Use a filter with a low to moderate flow rate to avoid stressing the fish.
   • Regular water changes are essential to keep ammonia and nitrate levels low.

5. Diet:

   • Black Comet Goldfish are omnivores and should be fed a varied diet including high-quality flakes, pellets, and fresh vegetables like peas and blanched spinach.
   • Occasional treats of live or frozen foods such as bloodworms and brine shrimp can be offered for enrichment.

6. Tank mates:

   • They are social and do well with other goldfish or similar peaceful species like weather loaches and some catfish.
   • Avoid aggressive or fin-nipping fish that may harass them, as their long fins make them vulnerable.

7. Behavior and Compatibility:

   • Black Comet Goldfish are active and may even recognize their owners. They appreciate interactive toys and environments.
   • Ensure tank mates are compatible in size and temperament to prevent stress or competition during feeding.
