Butterfly Japanese Koi (A grade) (Cyprinus Carpio)

Majestic, flowing, and breathtakingly beautiful — the Butterfly Japanese Koi (A Grade) is a premium selection of one of the most elegant koi varieties available. Distinguished by their dramatically elongated, flowing fins that trail gracefully through the water like butterfly wings, these A-grade specimens are hand-selected for superior colouration, pattern, and fin development. A true centrepiece for any large pond or indoor koi display.

Overview

Appearance — A Grade

Our A-grade Butterfly Koi are selected for exceptional quality — featuring vibrant, well-defined colour patterns, symmetrical markings, and the hallmark long, flowing fins that extend gracefully from the dorsal, pectoral, and caudal fins. Colour varieties may include kohaku (red and white), sanke, showa, and other classic koi patterns. As they grow, their fins continue to lengthen, becoming increasingly spectacular with age.

Water Parameters & Setup

• Temperature: 59 – 77°F (15 – 25°C)
• pH: 7.0 – 8.5
• Ammonia/Nitrite: 0 ppm (koi are sensitive to poor water quality)
• Pond Size: Minimum 1,000 gallons for a small group; larger is always better
• Filtration: Heavy-duty biological and mechanical filtration is essential
• Depth: Minimum 3 feet (90 cm) to protect from predators and temperature extremes
• Note: Butterfly Koi can also be kept in very large indoor aquariums (300+ gallons) as juveniles

Diet & Feeding

• Staple: High-quality koi pellets (wheat germ-based in cooler months, high-protein in warmer months)
• Treats: Watermelon, oranges, lettuce, peas, and earthworms
• Colour enhancers: Spirulina and carotenoid-rich foods help maintain vibrant colouration
• Important: Do not feed when water temperature drops below 10°C (50°F)

Compatibility

Butterfly Koi are peaceful and social. They do well with:

• Other koi varieties
• Large goldfish (Comets, Shubunkins)
• Pond-safe bottom feeders

Avoid housing with small fish that may be accidentally eaten, or aggressive species that may damage their flowing fins.

The Butterfly Japanese Koi (A Grade) is a long-term investment in living beauty — a fish that grows more magnificent with every passing year. With proper care, these stunning koi will be a centrepiece of your pond for decades to come.
