Kohaku

Cyprinus rubrofuscus

Red markings on a white body, without black patterning.

Red patches lie on a white ground. Their shapes and number vary between individuals.

Natural habitat: The species inhabits freshwater and can tolerate slightly brackish conditions; koi are domesticated ornamental forms.

Plan filtration and adult space for a large pond fish; unprotected planting can be damaged.

Appearance and identification

Compare the placement and edges of the red markings. This illustration shows a normally scaled, short-finned Kohaku appearance.

Watch females during spawning chases.

Requires a large pond, effective filtration and ongoing water-quality management.

Use appropriate koi feed and adjust to temperature and feeding response; do not rely on leftovers.

Assess size, feeding and spawning behaviour individually.

Protect roots and planting areas.
