Keeping Hillstream Loach in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: herbivore
  • Minimum tank size: 20 gallons (75 liters) for a small group
  • Compatibility: Excellent with other peaceful, cool-water, and high-oxygen tolerant species such as White Cloud Mountain Minnows, Danios, and other small, non-aggressive bottom dwellers. Avoid aggressive or fin-nipping species.
  • Special requirements: Requires a highly oxygenated aquarium with strong water flow, mimicking their natural hillstream environment. Abundant smooth rocks and driftwood for grazing and hiding are essential. A mature tank with established biofilm is crucial. They are sensitive to poor water quality and high temperatures.
