White Cloud Mountain Minnow
Also known as: Tanichthys albonubes
The White Cloud Mountain Minnow is a small, hardy cyprinid known for its striking iridescent bronze-green body and bright red fins, especially in males. The White Cloud Mountain Minnow originates from Native to the White Cloud Mountain area of Guangdong Province, China, and also found in parts of Vietnam and Laos in slow-moving streams and tributaries with clear, cool water., reaches 3.5 cm in captivity, typically lives 5, and is kept at [18, 24]C ([64, 75]F). Individual fish vary, so treat this as a general guide rather than a guarantee.

About the White Cloud Mountain Minnow
The White Cloud Mountain Minnow is a small, hardy cyprinid known for its striking iridescent bronze-green body and bright red fins, especially in males. It thrives in cool, well-oxygenated water and is often recommended for beginner aquarists due to its resilience and low maintenance needs. This species is active and enjoys swimming in the middle to upper levels of the tank, displaying natural schooling behavior when kept in groups. Despite its tropical origins, it tolerates cooler temperatures better than most tropical fish, making it suitable for unheated tanks in temperate climates.
Lifespan and health
With proper care, White Cloud Mountain Minnows typically live 3 to 5 years in captivity, though exceptional individuals may reach up to 6 years under optimal conditions—cool, clean water, low stress, and a nutritious diet significantly extend longevity. Their lifespan is notably longer than many similarly sized tropical fish due to their tolerance for cooler temperatures, which reduces metabolic stress; maintaining water temperatures consistently below 24°C (75°F) is linked to improved long-term health and vitality. Common health issues are rare but can include ich (white spot disease) if water quality deteriorates or temperatures fluctuate excessively, particularly above 26°C (79°F); fin rot may occur in overcrowded or poorly filtered tanks with high ammonia levels. Preventative care includes avoiding sudden temperature shifts, quarantining new fish for 2-4 weeks, and maintaining stable pH between 6.5-7.5. They are generally resistant to parasites and bacterial infections when kept in groups with adequate space and nutrition, making them one of the hardiest freshwater community fish available.
Overview
The White Cloud Mountain Minnow is a small, hardy cyprinid known for its striking iridescent bronze-green body and bright red fins, especially in males. It thrives in cool, well-oxygenated water and is often recommended for beginner aquarists due to its resilience and low maintenance needs. This species is active and enjoys swimming in the middle to upper levels of the tank, displaying natural schooling behavior when kept in groups. Despite its tropical origins, it tolerates cooler temperatures better than most tropical fish, making it suitable for unheated tanks in temperate climates.
Care and tank setup
For optimal care, maintain a minimum tank size of 38 liters (10 gallons) for a school of 6-8 White Cloud Mountain Minnows, though larger tanks (75+ liters / 20+ gallons) are preferable to support natural swimming behavior and stable water parameters. Use a fine gravel or sand substrate with plenty of live plants such as Java moss, Anubias, or Hornwort to provide cover and mimic their natural stream habitat; gentle filtration is essential to avoid strong currents that can stress these small fish. Water should be kept clean with weekly 25% water changes, and parameters monitored regularly—ammonia and nitrite must remain at 0 ppm, nitrate below 20 ppm, and dissolved oxygen levels high due to their preference for well-oxygenated environments. Feeding should consist of a varied diet: high-quality micro pellets or crushed flakes as a staple, supplemented 2-3 times per week with live or frozen foods like brine shrimp, daphnia, or microworms to enhance coloration and vitality. Avoid overfeeding; offer only what they can consume in 2-3 minutes per feeding. Tankmates should be peaceful, similarly sized species such as other small cyprinids (e.g., Zebra Danios, Ember Tetras), Corydoras catfish, or small shrimp like Amano or Cherry Shrimp; avoid aggressive or fin-nipping fish such as Tiger Barbs or large cichlids. A tight-fitting lid is recommended as they are known to jump occasionally, especially during feeding or when startled.
