• Plants (Java moss, Vallisneria, Anubias)

• Open swimming space

• Moderate water flow

• Dark substrate for color contrast

They enjoy clean, well-oxygenated water.

Diet

Golden Cloud Minnows are omnivores.

Feed them:

• High-quality flakes

• Micro pellets

• Frozen bloodworms

• Brine shrimp

• Daphnia

• Small insects

Varied diets help maintain bright coloration and health.

Tank Mates

Because they prefer cooler water, choose tank mates carefully.

Good tank mates:

• Other White Cloud Mountain Minnows

• Zebra Danios

• Corydoras (cool-water tolerant species)

• Hillstream loaches

• Small rasboras

Avoid:

• Tropical fish that require warm water (above 26°C)

• Aggressive fish

• Large predators

Breeding

White Cloud Minnows are very easy to breed.

Breeding Conditions

• Slightly warmer water (~22°C)

• Dense plants or moss

• Separate breeding tank recommended

Spawning Process

1. Males display bright colors and chase females.

2. Eggs are scattered among plants.

3. Eggs hatch in 36–48 hours.

Fry Care

Fry eat:

• Infusoria

• Liquid fry food

• Baby brine shrimp after a few days

Adults may eat eggs, but in planted tanks some fry often survive naturally.
