White Cloud Minnow Care Guide
Tanichthys albonubes
Key Takeaways
- White Cloud Minnow needs at least 10 gallons, with 20 gallons preferred.
- Keep water between 18-22°C and pH 6-8.
- Keep a group of at least 6 to reduce stress.
Actionable Setup Plan
- Keep 6+ white cloud minnows in a 10-gallon minimum, with a longer 20-gallon aquarium preferred for a larger school.
- Maintain cool water at 18-22°C and avoid placing an unheated tank where summer heat can push temperatures upward.
- Do not rely on temperature overlap alone for goldfish: large goldfish can still eat small minnows and create heavy waste.
Quick Facts
Size
Adults reach about 4 cm (1.5 in), so a school needs secure cover and tank mates that cannot swallow them.
Lifespan
They commonly live 3-5 years with cool, stable water and a proper school.
Minimum School Size
A 10-gallon tank is the minimum for 6 fish; more water volume and swimming length are better as the school grows.
Care Overview
White cloud minnows are hardy, cold-water fish that don't need a heater. They are peaceful schooling fish with subtle but attractive coloring.
Ideal Tank Setup
A 10+ gallon tank without a heater (they prefer cooler water). Keep in groups of 6 or more. They do well in unheated indoor tanks.
Food
Omnivores that eat small flake food, micro pellets, and small live or frozen foods. Feed 2 times daily.
Tank Mates
- Zebra danios
- Goldfish (similar temperature)
- Other cold-water species
Fish to Avoid
- Tropical fish (different temperature needs)
- Large aggressive fish
Common Problems
- Overheating in summer
Common Beginner Mistakes
- Using a tank smaller than 10 gallons, which makes water quality harder to keep stable.
- Ignoring adult size, group size, or temperament when choosing tank mates.
- Changing too much water or filter media at once before checking ammonia and nitrite.
