Overview
The cloud loach is a small, mostly peaceful stone loach for the bottom of a cool river tank. It is best with a little experience.
Did you know
The cloud loach's species name, nubigena, means born of the clouds. It refers to the fish's pattern, not to the cloud-wrapped mountains near its home at Putao.
Caring for the cloud loach
Give a small group of cloud loaches a tank of 20 gal (75 L) or more. Lay a stony floor of gravel and smooth stone, with enough broken-up cover for each fish to hold a small territory. A small group kept this way stays settled and active on the bottom.
Keep the water cool, at 64 to 75°F (18 to 24°C) and a pH of 6.5 to 7.5. Give it brisk current and high oxygen. Clean, moving water suits it better than warm, planted-tank conditions.
Feed fine sinking foods, frozen daphnia and small bloodworm. The cloud loach is mostly peaceful, and it is gentler on tank mates than its larger cousins simply because of its size. Choose calm, coolwater companions such as small danios and hill-stream fish that share its taste for oxygen and flow. Its breeding has not been recorded in the aquarium.
Good to know
Schistura nubigena is a stone loach of the family Nemacheilidae. In adults the dark bars partly fuse, and a row of pale, cloud-like spots forms along the back where they break apart.
In the wild
The cloud loach comes from the Mali Hka drainage near Putao, in the far north of Myanmar's Kachin State. Its home streams run cool and clear at the edge of the eastern Himalaya.
