What Ranchu Goldfish look like

Ranchu are dorsal-less fancy goldfish with a rounded body, arched back, tucked tail, and head growth. The back line is smoother and more arched than a Lionhead.

Behavior & temperament

Ranchu are slow, delicate fancy goldfish. They need smooth decor, gentle flow, excellent water quality, and similarly slow fancy tank mates. They should not compete with long-bodied goldfish.

Diet & feeding

Ranchu Goldfish are omnivores that do best on sinking goldfish pellets or gel food, blanched greens, daphnia, brine shrimp, and occasional bloodworms. Avoid overfeeding and maintain strong filtration.

Behind the name

Ranchu is the Japanese name for this dorsal-less fancy goldfish variety.
