Behavior and Compatibility

The Comet is a very active and fast fish that spends a lot of time swimming. It is social and can be kept in groups with other common or Shubunkin goldfish. However, it is not recommended to keep them with slower goldfish varieties, such as those with flowing fins, as they may be outcompeted for food during feeding times.

They are also curious and like to sift through the substrate for food, which can sometimes disturb aquatic plants that are not well-rooted.

Diet

The Comet is an omnivore and should receive a balanced diet:

• Main foods: Pellets or flakes specifically for goldfish
• Fresh foods: Vegetables (spinach, zucchini, shelled peas), small amounts of fruit
• Proteins: Bloodworms, daphnia, (occasionally)
• Feeding frequency: 2 to 3 times a day in small quantities to avoid water pollution

Specifics and Tips

• They produce a lot of waste, requiring powerful filtration and regular water changes (30% weekly).
• They tolerate winter well in outdoor ponds, as long as the water does not freeze completely.
• They tend to grow quickly and require sufficient space to thrive.

The Comet goldfish is a fascinating variety, both hardy and elegant, suitable for beginners and experienced aquarists looking for a dynamic coldwater aquarium.
