About

The Butterfly Tail Calico Goldfish features the iconic butterfly-shaped tail (best viewed from above) combined with nacreous multicolour calico scaling of orange, black, white, and blue. The combination of this rare tail form and calico colouration is especially prized by collectors and show enthusiasts in the Benelux region. Recommended for experienced fancy goldfish keepers who can provide optimal conditions.

Care Guide

Provide excellent filtration — fancy goldfish produce heavy waste. Maintain clean, well-oxygenated, cool water (10–22°C). Feed sinking or pre-soaked pellets to reduce swim-bladder issues. House only with other slow fancy goldfish of similar size. Avoid sharp decorations that damage elaborate fins. Regular water changes essential.
