Keeping Korean Aucha Perch in an aquarium requires the right conditions.

Aquarium Information

  • Care level: advanced
  • Temperament: peaceful
  • Diet: carnivore
  • Minimum tank size: 75 gallons (280 liters)
  • Compatibility: Best kept in a species-specific tank or with other peaceful, cool-water native Korean fish of similar size. Avoid aggressive or fin-nipping species.
  • Special requirements: Requires highly oxygenated, clean water with strong current. A well-filtered tank with a river manifold or powerheads to simulate natural flow is essential. Substrate should consist of fine gravel and sand with smooth rocks and driftwood for hiding places. Live plants are beneficial but should be robust enough to withstand current. Sensitive to poor water quality and requires frequent water changes.
