Blue-Tailed Hillstream Loach (Beaufortia kweichowensis)Overview
The Blue-Tailed Hillstream Loach is a fascinating freshwater fish prized for its unique appearance and ability to thrive in fast-flowing waters. With an elongated, flattened body and vibrant blue hues on its tail, this loach is a popular choice for well-maintained river-style aquariums. It is an efficient algae grazer and an excellent addition to a peaceful community tank.
Origin
Native to the fast-moving rivers and streams of China, particularly in the Kweichow (Guizhou) and Guangxi provinces, this species is well-adapted to life in high-oxygen environments with rocky substrates and strong currents.
Feeding
Blue-Tailed Hillstream Loaches are omnivorous, with a strong preference for biofilm and algae. In captivity, they should be provided with:
Algae wafers
Blanched vegetables (zucchini, spinach)
High-quality sinking pellets
Frozen and live foods (daphnia, bloodworms, and brine shrimp) as occasional protein sources
A well-established tank with natural algae growth will help meet their dietary needs.
Tank Mates
This species is peaceful and does well with other non-aggressive fish. Ideal tank mates include:
Other hillstream loaches
Small schooling fish (rasboras, danios, white cloud mountain minnows)
Dwarf shrimp and non-aggressive bottom dwellers
Avoid housing them with large, aggressive fish that may outcompete them for food or disturb them.
Aggression
Blue-Tailed Hillstream Loaches are generally peaceful but may show mild territorial behavior toward their own kind if space is limited. Providing ample hiding spots and multiple grazing areas helps minimize aggression.
Experience Level
Moderate – While not overly difficult to keep, they require specific water conditions, strong filtration, and high oxygen levels, making them better suited for aquarists with some experience.
Water Parameters
Temperature: 68–75°F (20–24°C)
pH: 6.5–7.5
Hardness: 5–15 dGH
Flow: Strong (simulating river currents)
Tank Size: Minimum 20 gallons, preferably larger with a long footprint
Additional Notes
To replicate their natural habitat, use smooth river stones, sand or fine gravel substrate, and driftwood. A high-flow filter or powerhead is essential to maintain water movement and oxygenation.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.
