Oranda goldfish

Carassius auratus

Developed headgrowth together with an erect dorsal fin

Orandas develop headgrowth while retaining a dorsal fin and double tail. The dorsal fin separates them from ranchu and lionhead forms. Chinese trade labels do not map reliably to English breed names; hood coverage and tail shape vary between regional strains.

Adult length: About 10 cm
Lifespan: Up to 30 years
pH: 7–8.4
Hardness: 5–19 dGH

Natural habitat: Wild habitats include rivers, lakes, ponds and ditches, often in vegetated still or slow water; ornamental goldfish are domesticated forms.

Excessive headgrowth may obscure the eyes; watch feeding access. Avoid sharp decor and competitive feeders. The illustration does not establish health or show quality. Swimming and feeding ability vary among forms. Provide filtration, oxygenation and maintenance.
