Our Guide To Keeping Black Comet Goldfish

1. About Fish Species:

   • Scientific name: Carassius auratus
   • Common name: Black Comet Goldfish
   • Family: Cyprinidae
   • Origin: Bred from the Common Goldfish, originally native to East Asia
   • Adult length: 15 to 30 cm
   • Lifespan: 10 to 20 years (can exceed 20 with proper care)
   • Diet: Omnivore
   • Care Level: Easy

2. Tank Setup:

   • Black Comet Goldfish need spacious environments. A minimum of 100L per fish is recommended in an aquarium, or they can be kept in outdoor ponds.
   • They appreciate open swimming areas, smooth decorations, and hardy plants such as Anubias or Hornwort that can tolerate cool water.

3. Water Parameters:

   • Maintain a pH between 6.5 and 7.5.
   • Optimal temperature range is 16 to 24°C (60 to 75°F). They are cold-tolerant and suitable for temperate outdoor ponds.

4. Filtration and Water Flow:

   • Use a good-quality filter to manage waste and maintain clean water, as goldfish produce a moderate bioload.
   • Moderate water flow is ideal, with adequate oxygenation provided by surface agitation or air stones.

5. Diet:

   • Feed high-quality goldfish flakes or pellets as a staple diet.
   • Supplement with vegetables (blanched peas, spinach), live or frozen foods (bloodworms, daphnia), and occasional fruit treats.

6. Tank mates:

   • Black Comets are peaceful and do well with other single-tail goldfish varieties like common or comet goldfish.
   • Avoid slow-moving fancy goldfish and tropical species with incompatible care needs.

7. Behavior and Compatibility:

   • Black Comet Goldfish are lively, fast swimmers that enjoy open space and social interaction with their own kind.
   • They are non-aggressive and thrive in groups, making them a great addition to peaceful community ponds or aquariums.
