Overview
The cross loach is a tiny, peaceful schooling loach for a planted nano tank. It is a fish of middling difficulty.
Did you know
The cross loach is one of the few loaches that spends much of its time suspended in midwater rather than resting on the bottom. It hovers and swims in open water in a loose group, which is where the name hovering loach comes from.
Caring for the cross loach
Keep cross loaches in a group of at least 8 to 10, in a tank of 14 gal (54 L) or more. Give them plenty of plants and gentle flow. A nano or planted community suits them best.
Keep the water clean, at 68 to 77°F (20 to 25°C) and a pH of 6.0 to 7.5. Soft to moderately hard water suits it well.
The cross loach is a micropredator. Feed small live and frozen foods such as daphnia, baby brine shrimp and microworm, plus fine dry foods.
It is peaceful and small, so keep it with other nano fish such as small rasboras, pygmy corydoras and shrimp. It is one of the more willing loaches to spawn at home. In a settled group it scatters its eggs into fine-leaved plants and moss, and breeding it is a moderate challenge.
Good to know
The cross loach is a tiny stone loach in the family Nemacheilidae. It has passed through the genera Nemacheilus and Yunnanilus before settling in Micronemacheilus.
In the wild
The cross loach is native to central Vietnam. It lives in slow, weedy streams and pools, among dense vegetation.

Does a cross loach need a group?
Yes. A cross loach is a schooling species and should be kept in a group, not singly.
How does a cross loach breed?
