Can Akahire be kept without a heater?

Yes, they're a hardy species that tolerates cool water fairly well, so they can be kept without a heater as long as room temperature doesn't drop too low. Just avoid sudden temperature swings and match the water temperature during water changes.

How many should I keep together?

Can they live with other fish?

Yes, their calm, low-aggression temperament makes them easy to keep alongside other small fish of similar size. Be cautious with more aggressive species, since they may nip at Akahire fins.

What should I feed them?

Standard flake or pellet food works well as their main diet. Choosing a small pellet size suited to their mouths helps reduce leftover food in the tank.

How big do they get and how long do they live?

Adults stay compact at around 3 to 4 cm, with a typical lifespan of about 3 to 5 years. Their small size makes them easy to start with in a modest tank.

White Cloud Mountain Minnow

The White Cloud Mountain Minnow, known in Japan as Akahire, is a small freshwater fish native to China, named for the reddish tint of its fins. Its body has a soft olive hue, and a school swimming together gives a tank a cool, lively feel. Calm and peaceful by nature, it gets along well with other fish and is hardy enough to tolerate temperature swings, so it can be kept without a heater. This resilience makes it a popular first fish for beginners. It eats standard flake or pellet food, keeping daily care simple, and stays compact at just 3 to 4 cm as an adult, making it well suited to smaller tanks kept in groups.

About White Cloud Mountain Minnow

The White Cloud Mountain Minnow is a hardy, heater-free freshwater fish from China, prized by beginners for its peaceful nature and lively schooling behavior.

7 things to know before welcoming a White Cloud Mountain Minnow

1Heater-Free Housing
Akahire tolerate cool water well and can be kept without a heater as long as room temperature doesn't drop too low. Still, avoid sudden temperature swings and match the water temperature when doing water changes.
2Better in Groups
This species has a natural schooling instinct, so keeping several together lets you see their natural behavior. A group tends to settle in and feel more secure than a single fish kept alone.
3Peaceful Tank Mate
Akahire are calm and low in aggression, making them easy to keep alongside other small fish of similar size. Avoid pairing them with more aggressive species, since their fins can get nipped.
4Standard Flake Food Works
They thrive on standard flake or pellet food, so there's no need for live food. Choosing a small pellet size suited to their mouths helps prevent leftover food from fouling the tank.
5A 3-5 Year Lifespan
With proper care, Akahire typically live around 3 to 5 years, making them a relatively long-lived choice among small fish. Consistent water quality maintenance is the key to a long life.
6Stays 3-4 cm as an Adult
Adults stay compact at around 3 to 4 cm, so you don't need a large tank to get started. Even a small tank can comfortably house a small school.
7Avoid Sudden Water Changes
Though hardy, Akahire can be stressed by abrupt shifts in water quality or temperature. Acclimate new arrivals carefully and give them a stable environment to settle into.
