Species Overview
These active and adaptable fish come from the cool, slow-moving streams of southern China. White Clouds are ideal for unheated tanks or outdoor tubs in temperate climates. Their shimmering silver bodies, red fins, and gold accents make them visually appealing despite their small size. They’re best kept in groups of 6 or more.
Appearance and Behavior
White Clouds have a slim, torpedo-shaped body with red or orange-tipped fins and a golden-white stripe along their side. They are lively swimmers that spend most of their time in the mid to upper tank levels. In groups, they school beautifully and display natural social behaviors.
My Experience: I’ve kept White Clouds in both indoor and outdoor setups. They’re incredibly hardy and do especially well in unheated tanks. Their peaceful nature makes them great community tank residents.
Ideal Tank Setup
Start with a 10–15 gallon tank or larger. Use gravel or sand substrate and include live plants like hornwort, Java fern, or water wisteria. They enjoy moderate flow and good oxygenation. Filtration should be gentle but consistent.
- Temperature: 60–72°F
- pH: 6.0–8.0
- Hardness: 5–19 dGH
Compatible Tank Mates
White Clouds are peaceful and can live with:
- Zebra Danios
- Pygmy Corydoras
- Cherry Shrimp
- Mystery Snails
- Rosy Barbs (in cool setups)
- Guppies (if kept in cooler water)
Avoid aggressive or fin-nipping fish. They also do great in species-only tanks.
Feeding and Diet
White Clouds eat just about anything: flakes, micro pellets, and frozen or live foods like brine shrimp and daphnia. Feed twice daily in small portions. A varied diet helps bring out their colors and supports breeding.
Breeding White Cloud Mountain Minnows
They’re one of the easiest fish to breed. In a planted tank or outdoor tub, they often spawn without intervention. Males chase females during courtship, and eggs are scattered among plants. Adults rarely eat eggs but can be separated for better fry survival. Fry hatch in 2–3 days and can be fed infusoria or powdered food.
What I’ve Learned: Outdoors, they breed like clockwork. Indoors, you can breed them in a simple bare-bottom tank with spawning mops or moss. No heater needed—just a bit of patience.
