White Cloud Mountain Minnow

White Cloud Mountain Minnow (Tanichthys albonubes)

The White Cloud Mountain Minnow is a charming and hardy freshwater schooling fish, admired for its shimmering silver body, iridescent green-blue stripe, and flashes of red on its fins. Native to cool mountain streams in southern China, this peaceful nano fish has become a favorite among aquarists for its adaptability, active behavior, and suitability for planted aquariums and unheated setups. Its small size, vibrant appearance, and easy care requirements make it an excellent choice for both beginner and experienced fish keepers.

White Cloud Mountain Minnows are peaceful, social fish that thrive when kept in groups, where they display their most natural behaviors and feel secure. They spend much of their time swimming through the middle and upper levels of the aquarium, darting gracefully among plants and open swimming areas. Males typically show brighter coloration and more elongated fins, especially during courtship displays, while females tend to have rounder bodies and softer coloration. Their gentle temperament makes them excellent companions for other peaceful fish with similar temperature preferences.

These hardy minnows thrive in well-planted aquariums with clean, well-oxygenated water, gentle flow, and plenty of open swimming space. Dense vegetation, floating plants, rocks, and driftwood help recreate their natural stream environment while providing shelter and visual structure. Unlike many tropical species, White Cloud Mountain Minnows prefer cooler water and can often be kept successfully without a heater in suitable indoor environments. A varied diet of quality flakes, small pellets, frozen foods such as daphnia and baby brine shrimp, and occasional live foods will help maintain their health, activity, and vibrant coloration.
