Tank Setup
The White Cloud Mountain Minnow (Tanichthys albonubes) requires a minimum tank size of 10 gal. For a species this size, a larger tank is always better — more water volume means more stable parameters and a healthier environment.
Water parameters should be maintained within the following ranges: temperature 16–22°C, pH 6.0–8.0, and hardness 5–20 dGH. These are relatively tolerant fish that adapt to a range of conditions.
Provide appropriate hiding places, a suitable substrate, and planted areas to match the natural behaviour of this species.
Tank Mates
White Cloud Mountain Minnow are peaceful fish. They work well in community tanks with similarly-sized peaceful species.
Compatible tank mates include: Zebra Danio, Cherry Barb, Corydoras, Goldfish (juveniles), Bristlenose Pleco. Avoid housing with aggressive or much larger fish.
Schooling requirements: 6+ required. Keeping them in adequate numbers is essential for their wellbeing.
Diet & Feeding
White Cloud Mountain Minnow are Omnivore. Feed a varied diet to ensure optimal health and colouration.
Omnivore — flakes, micro pellets, frozen daphnia
Feed small amounts 1–2 times daily. Only provide what the fish can consume within 2–3 minutes to prevent overfeeding and water quality issues. Supplement with live or frozen foods for optimal health and colour.
Common Health Issues
Like all aquarium fish, White Cloud Mountain Minnow can be susceptible to common diseases including ich (white spot disease), fin rot, and bacterial infections. This species is generally hardy and disease-resistant when kept in good conditions.
Prevention is always better than treatment. Maintain stable water parameters, avoid overfeeding, quarantine new fish before adding them to the main tank, and perform regular water changes. A regular maintenance routine will prevent most health issues.
If disease does occur, isolate affected fish in a quarantine tank and treat appropriately. Always research medication compatibility before use — some treatments are toxic to invertebrates and scaleless fish.
Breeding
Breeding White Cloud Mountain Minnow is possible in the home aquarium.
Provide appropriate breeding conditions — caves or hiding places for egg-laying species. Condition breeding pairs with high-quality foods before attempting to spawn them.
Many White Cloud Mountain Minnow will breed readily without intervention. Be prepared to remove eggs or fry if you want to raise them — adult fish may eat their own young.
