Overview
The red hillstream loach is a flat, disc-shaped loach that presses itself to rocks in strong, cool flow. It is a step up from the easiest fish.
Did you know
The red hillstream loach moves across glass and rock in short, gecko-like scoots. Its flattened body works as a living suction cup.
Caring for the red hillstream loach
Keep a small group in a tank of 24 gal (90 L) or more, with strong flow and smooth rockwork. Stones lit brightly enough to grow algae give them grazing surface and a place to rest.
Keep the water cool, very clean and highly oxygenated, at 64 to 75°F (18 to 24°C) and a pH of 6.5 to 7.5. The current should be strong enough to mimic a mountain rapid, often from an oversized filter or an added powerhead. Warm, still water leaves them listless and short-lived.
It grazes algae and biofilm. Supplement with vegetable-based sinking foods, blanched vegetables and the occasional frozen treat.
The red hillstream loach is peaceful toward tank mates and suits cool-water fish such as white cloud minnows, danios and other hillstream loaches. It will still defend a favorite grazing rock from its own kind. Breeding it is hard.
Good to know
The red hillstream loach, Beaufortia leveretti, is a member of the family Gastromyzontidae. Its fused, wing-like paired fins form a suction disc that holds it to bare rock against fast water. It is closely related to the common butterfly hillstream loach, and the reddish tint to its fins tells it apart.
In the wild
The red hillstream loach is native to fast, rocky streams of southern China and northern Vietnam. It clings to stones in cool, oxygen-rich current.
