Ranchu (Carassius auratus)

The "king of goldfish" — a selectively bred fancy variety prized for its rounded body, absence of a dorsal fin, and distinctive head growth (wen). With their charming waddle-swim and inquisitive nature, Ranchus are a beloved show fish for dedicated coldwater hobbyists.

Care at a Glance:

  • Minimum Tank Size: 75+ litres per fish (large tank with gentle filtration)
  • Temperature: 18–22°C
  • pH Range: 6.5–7.5
  • Temperament: Peaceful, slow-moving
  • Diet: Omnivore — sinking pellets, gel food, frozen foods, blanched vegetables
  • Max Size: 15–20cm
  • Lifespan: 10–15 years
  • Care Level: Intermediate (sensitive swim bladder, requires pristine water quality and careful feeding)

Tank Mates: Other fancy goldfish varieties (Oranda, Ryukin, Black Moor). Avoid slim-bodied goldfish (commons, comets) and any fast or nipping species that may outcompete or stress them.
