Assorted Comet Goldfish

Assorted Comet Goldfish - Classic Cold-Water Pond Fish, Mixed Colours

The Assorted Comet Goldfish is the classic single-tail pond goldfish, sold as a mixed colour run so no two fish are quite the same — expect everything from solid orange to red and white patterned individuals within the group.

True cold-water fish, comets do not need a heater and are happiest in a large, well-aerated tank or outdoor pond where their long, flowing single tail and fast, darting swimming style have room to shine. They are exceptionally hardy and grow quickly, so their housing needs to keep pace with them.

At N8 Aquatics, our fish are carefully raised and conditioned to ensure healthy stock suited to home aquariums.

Ideal Habitat and Care

A spacious 200 L or larger tank, or ideally an outdoor pond, gives this fast-growing cold-water fish the room it needs as it matures.

• Temperature: 10–24°C, no heater required
• pH: 7.0–8.0
• Water Flow: Moderate to strong — comets are powerful swimmers and appreciate good water movement
• Maintenance: Strong filtration and frequent partial water changes, as these fish produce heavy waste

Diet

An easy-feeding omnivore, the Comet Goldfish will eat readily but shouldn't be overfed given how messy the species can be.

• Goldfish flake or pellet as a daily staple
• Blanched vegetables such as peas or zucchini
• Occasional frozen bloodworm or brine shrimp
• Feed in small amounts several times a day rather than one large feed

Compatibility

As true cold-water fish, comets and shubunkins are outgoing, fast-growing swimmers best paired with other single-tail goldfish that can keep pace with them at feeding time.

Suitable tankmates include:

• Other Comet or Shubunkin Goldfish
• Common or fancy single-tail goldfish of a similar size
• Large, hardy pond fish
• White Cloud Mountain Minnows in unheated setups

Avoid aggressive or fin-nipping species.
