KOI BUTTERFLY ASSORTED (Cyprinus carpio) 2.5–3.75″ A2404T

Premium Juvenile Butterfly Koi for Canadian Ponds and Water Gardens

The Assorted Butterfly Koi (Cyprinus carpio) is a spectacular ornamental pond fish prized for its long flowing fins, graceful swimming, and brilliant assortment of colours and patterns. Also known as Longfin Koi, Butterfly Koi bring elegance and movement to ponds, water gardens, and large aquatic displays.

These 2.5–3.75-inch juvenile Butterfly Koi are perfect for hobbyists who want to raise premium koi from a young age. Each fish is individually selected for its health and quality and may feature striking combinations of white, red, orange, yellow, black, metallic silver, gold, or calico markings. As they mature, their colours intensify and their flowing fins become even more impressive.

Butterfly Koi are hardy, peaceful, and intelligent fish that can recognize their owners and often learn to hand-feed. With proper care, they can live for decades and become magnificent centrepieces in any outdoor pond.
