Goldfish – Shubunkin Comet 4cm

Shubunkin Goldfish – Calico Patterns and Lively Swimming for Coldwater Tanks!

The Shubunkin Goldfish stands out with its distinctive calico colouring that mixes blue, red, orange, black, and white across a slender body and long fins. This hardy variety originates from selective breeding in Asia and moves actively through the water. Aquarists choose Shubunkin Goldfish for outdoor ponds or spacious aquariums since they tolerate cooler temperatures and add constant motion with minimal fuss.

Size and Lifespan

These goldfish currently measure around 10–15 cm depending on age. They grow to a maximum of up to 25 cm in roomy setups. With regular water changes, balanced feeding, and adequate space, they live 10 to 15 years, and some reach 20 years in well-managed ponds.

Ideal Tank Setup

Arrange a large aquarium or pond that provides open swimming lanes for these energetic fish. Install powerful filtration to cope with waste and keep temperatures cool and stable. Avoid pointed decorations since they can damage flowing fins during active movement.

To replicate its natural habitat:

• Use smooth gravel or sand substrate for comfort
• Include hardy plants and smooth rocks for shelter
• Leave wide open areas for constant swimming
• Secure a lid or pond cover to prevent escapes

Compatible Tank Mates

Keepers often house Shubunkin Goldfish in groups or with other coldwater goldfish varieties in large systems. Introduce new fish slowly and ensure all share similar activity levels to maintain harmony.

Suitable tank mates include:

• Comet goldfish for matching speed
• Common goldfish in spacious ponds
• Other Shubunkins to form active schools
• White Cloud Mountain minnows in cooler water

Diet and Feeding

Offer high-quality goldfish pellets or flakes daily because they supply complete nutrition for growth and colour. Supplement with blanched peas, zucchini, or frozen brine shrimp several times weekly. Feed small portions 2–3 times per day and remove any uneaten food to protect water quality.

Breeding and Behaviour of Shubunkin Goldfish

Males chase females during spawning and scatter eggs among plants or surfaces in slightly warmer water. Adults eat eggs if left in place, so keepers transfer them to separate tanks. These goldfish swim actively, forage constantly, and interact socially in properly sized groups without aggression.
