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)
  • Compatibility: Excellent with other peaceful, cool-water fish that can tolerate strong currents, such as other hillstream loaches, Danios, White Cloud Mountain Minnows, and some smaller gobies. 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. The tank should be mature with established biofilm for feeding. Avoid high temperatures and poor water quality, as these can quickly lead to stress and disease.
