Natural habitat

The Hillstream Loach is found in fast-flowing rivers and streams characterized by rocky substrates and well-oxygenated waters. They thrive in environments with consistent water flow which aids their feeding habits.

Where they are found

This species is primarily found in the waterways of Vietnam, where they inhabit clean, fast-flowing streams with a variety of substrates including sand and small gravel.

Aquarium care

For optimal care, the aquarium should replicate their natural environment with strong water flow and high oxygen levels. A tank designed with smooth stones, open swimming areas, and minimal substrate will better satisfy the loaches' grazing habits. Regular monitoring of water conditions is crucial as they are sensitive to temperature fluctuations and ammonia levels.

Feeding

Feed a varied diet including live or frozen food like bloodworms and tubifex, alongside high-quality sinking pellets and algae wafers. They also graze on algae in the aquarium, aiding in tank cleanliness.

Compatibility

These loaches are generally peaceful and should be kept in groups of at least three. Compatible tank mates include coolwater fish such as White Cloud Mountain Minnows and Otocinclus, as well as other Hillstream Loach species. Avoid keeping them with aggressive or tropical species that prefer warmer waters.

Breeding

Breeding Tiger hillstream loaches can be achieved in a dedicated breeding tank with a sponge filter for optimal water quality. A slight increase in temperature can encourage spawning behaviors. Once the fry are free-swimming, they should be fed infusoria until they are large enough to accept other foods.
