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.

Lasts a while for the price

Honestly, the best quality socks for the price. Last a long time and lots of sport and non-sport usage. Trim your toe nails though, this isn't immune to dank toe nail care.

Great Quality Socks!
Number of Items: 6, Color: Black (6-pairs), Size: Large
These Under Armour no-show socks are perfect—comfortable, breathable, and they stay in place all day without slipping. The fabric feels durable yet lightweight, and they wash up nicely without shrinking. Great value for a 6-pack, and they fit true to size. Exactly what I needed!

Good for a few uses
Number of Items: 6, Color: Steel Assorted (6-pairs), Size: Large
Elastic breaks down after a few washes and they become "quitters" and slide down into your sneaker. Very soft and comfortable for maybe a dozen wears
