Calico Oranda Goldfish 6.5cm

The Calico Oranda Goldfish (Carassius auratus var.) is a breathtaking fancy goldfish variety, combining the elegant flowing double fantail fins and distinctive fleshy wen (head growth) of the Oranda with a stunning calico colouration — a rich mosaic of red, orange, black, white, and blue-grey patches that makes every individual fish completely unique. At 6.5cm, these are well-developed fish with established wens and beautiful finnage, ready to become the centrepiece of a dedicated fancy goldfish aquarium.

Care Guide

• Tank Size: Minimum 120L for one or two fish; fancy goldfish are heavy waste producers — robust filtration is essential
• Water Parameters: pH 7.0–8.0 | Temp 18–24°C | Prefers cool, well-oxygenated water; avoid high temperatures
• Diet: Omnivorous — sinking goldfish pellets or gel food preferred to reduce air ingestion; supplement with blanched vegetables, daphnia, and bloodworm; avoid floating foods where possible
• Temperament: Peaceful; best kept with other fancy goldfish of similar size and swimming ability — avoid housing with fast-moving single-tailed goldfish or aggressive species
• Tank Setup: Smooth substrate (sand or rounded gravel); avoid sharp décor that could damage the wen or fins; good filtration and regular water changes essential
• Skill Level: Intermediate
• Max Size: 20–25cm
