The White Cloud Mountain Minnow (Tanichthys albonubes) is a small, hardy freshwater fish renowned as an ideal "starter fish" for beginners. Originally discovered in the cool streams of the White Cloud Mountains in southern China, it is often called the "Poor Man's Neon Tetra" due to its affordability and striking silver-green body with a bright red tail.
Key Characteristics
Size: They typically reach about 1.5 inches (4 cm) in length.
Temperament: Extremely peaceful and active; they should be kept in schools of at least 6 to 10 to feel secure and display their best colors.
Lifespan: Generally 3 to 5 years, though some can live up to 7 years in optimal conditions.
Varieties: Popular aquarium strains include the Golden Cloud, Long-finned Meteor Minnow, and the similar Vietnamese White Cloud (Tanichthys micagemmae).
Care and Tank Requirements
Unlike many tropical fish, White Clouds thrive in cooler water and often do not require a heater.
Temperature: 14–22°C (57–72°F) is ideal. Exposure to temperatures consistently above 25°C (77°F) can shorten their lifespan.
Tank Size: A minimum of 10 gallons (38 liters) is recommended.
Water Parameters: pH of 6.0–8.5 and a hardness (dH) of 5–19.
Diet: Opportunistic omnivores; they accept high-quality flakes, micro-pellets, and frozen treats like daphnia or brine shrimp.
