Behavior and tank mates

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

It is also curious and likes to dig in the substrate for food, which can sometimes disturb aquatic plants that are not well-rooted.

Feeding

The Comet is omnivorous and should receive a balanced diet:

• Main foods: Specific pellets or flakes 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% per week).
• 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 both beginners and experienced aquarists looking for a dynamic coldwater aquarium.
