Keeping Hillstream Loach in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: omnivore
  • Minimum tank size: 20 gallons (75 liters) for a small group
  • Compatibility: Excellent with other peaceful, cool-water, high-oxygen demanding fish such as Danios, White Cloud Mountain Minnows, and other small loaches. Avoid aggressive or fin-nipping species.
  • Special requirements: Requires a highly oxygenated aquarium with strong water flow, mimicking their natural hillstream environment. A powerhead or strong filter outflow directed along the substrate is essential. Abundant smooth rocks and pebbles for grazing and hiding are crucial. They are sensitive to poor water quality and require pristine, well-filtered water with regular water changes. Avoid high temperatures.
