About

Butterfly Showa merges the bold black (sumi), red (hi), and white (shiro) Showa Sanshoku patterning with graceful longfin extensions on all fins. The dramatic colour combination paired with flowing fins makes this one of the most spectacular pond fish available. A standout variety for serious pond collectors who want maximum visual impact.

Care Guide

Requires a large, well-filtered pond (2,000L+). Maintain excellent water quality — the longfins are susceptible to fin deterioration in poor water. Feed quality koi pellets. Seasonal feeding adjustment essential: reduce below 10°C, stop below 6°C. Provide minimum 1m depth for winter.
