Sarasa Comet Goldfish (Carassius auratus)
The Sarasa Comet Goldfish (Carassius auratus) wears the classic red and white sarasa pattern on a sleek, single-tailed comet body. These are hardy, peaceful, beginner-friendly fish and one of the best choices for ponds and spacious coldwater aquariums. Our current group runs 3 to 4 inches, young fish with their color pattern already set. Browse the rest of our freshwater livestock for tank mates.
Care Guide
- Tank or pond: comets are active swimmers that reach 10 to 12 inches. Plan on 40 gallons or more for the first fish indoors, or an outdoor pond where they truly shine.
- Coldwater, no heater: comfortable from 60 to 75°F. They handle Georgia winters outdoors in a pond with adequate depth.
- Water: pH 7.0 to 8.0, moderate hardness. Very forgiving of parameter drift once the tank is cycled.
- Filtration: goldfish are messy eaters, so oversize the filter and keep up with weekly water changes.
- Feeding: omnivorous grazers. A quality goldfish pellet or flake as the staple, with gel food and blanched veggies as treats.

Compatibility
Sarasa Comets are ideal pond mates for other single-tailed goldfish like the Shubunkin, and they mix well with dojo loaches and other coldwater species. Skip tropical community fish, since the temperature needs do not line up, and be careful pairing fast comets with slow-swimming fancy goldfish such as the Panda Butterfly: comets usually outcompete them for food in the same tank.

FAQ
Can they live outside year round?
Yes. Comets are among the hardiest pond fish available. In a pond with 18 inches or more of depth they overwinter outdoors just fine in our climate.
How big will it get?
Expect 10 to 12 inches over a few years in a pond, somewhat less in an aquarium. They grow fast with space and good food.
Can I keep one with tropical fish?
Not recommended. Goldfish want cooler water than a tropical community, and they will eventually outgrow most community tanks anyway.
How many can I add at once?
Figure one comet per 40 gallons indoors, or a small group in a pond. They are social and do best with at least one companion goldfish.
