Overview The Red-Tailed Hillstream Loach is a striking and uncommon freshwater fish known for its streamlined body, vibrant red tail, and fascinating behavior. This species is well-adapted to fast-flowing, oxygen-rich waters and is ideal for well-maintained river-style aquariums. Their unique appearance and peaceful nature make them a great addition to a well-researched setup. Origin Native to the fast-flowing streams and rivers of Southeast Asia, particularly in Malaysia and Indonesia, these fish thrive in cool, well-oxygenated waters. Their natural habitat consists of rocky riverbeds where they graze on biofilm and small invertebrates. Feeding Red-Tailed Hillstream Loaches are omnivorous, primarily feeding on biofilm, algae, small invertebrates, and microorganisms found on surfaces. In captivity, they should be provided with: Algae-based foods (such as spirulina wafers) Blanched vegetables (zucchini, spinach) Small live or frozen foods (daphnia, brine shrimp, bloodworms) High-quality sinking pellets or wafers It is crucial to offer a varied diet to maintain their health and vibrant colours. Tank Mates This species is peaceful and does well in community tanks with other non-aggressive fish that thrive in similar water conditions. Ideal tank mates include:
 Small, peaceful characins (e.g., rasboras, danios)
 Other hillstream loaches or bottom-dwellers (e.g., Sewellia, Gastromyzon species)
 Small, peaceful gouramis or dwarf cichlids
 Shrimp and snails (though some may be nibbled on) Avoid keeping them with large, boisterous, or aggressive fish such as cichlids, barbs, or territorial bottom-dwellers. Aggression This species is non-aggressive and typically peaceful, but they can be territorial towards their own kind, especially if space is limited. Keeping them in small groups (3–5 individuals) helps distribute aggression, provided there are enough hiding spots. Experience Level Intermediate – While not overly difficult to keep, Red-Tailed Hillstream Loaches require specific water flow, oxygenation, and water quality to thrive. They are best suited for aquarists with some experience in maintaining river-style tanks. Water Parameters Temperature: 20–26°C (68–79°F) pH: 6.5–7.5 Hardness: 5–15 dGH Flow: Strong, well-oxygenated water with high filtration Tank Size: Minimum 20–30 gallons with a large footprint, as they prefer horizontal swimming space Key Care Tips Provide high water flow and aeration using a strong filter or powerhead
Use smooth river rocks and driftwood to replicate their natural habitat
