Malabar Danio
Danio sp.
The Malabar Danio (Danio sp.) is a peaceful fish that's easy to keep. Give it a tank of at least 180 litres (48 US gallons), water held at 64-77°F, and a pH of 6-8. Always keep a group of at least 6 - they feel safest in numbers.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Malabar Danio Tank Setup
Give them a tank of at least 180 litres (48 US gallons). As open-water swimmers they care more about swimming length than height, so a longer tank is ideal. Keep the water at 64-77°F with a pH around 6-8, and avoid sudden swings. Always keep a group of at least 6 of their own kind - kept alone or in pairs they tend to turn shy, nippy, or wash out in colour. They reach about 13 cm as adults, so don't be misled by the small juveniles sold in stores.
What Do Malabar Danios Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Malabar Danio Tank Mates
Keep in groups of at least 6. The Malabar Danio is peaceful, which is the first thing to weigh up when you choose tank mates. It's a shoaling fish, so settle a group of 6 or more of its own kind before adding anything else - a stressed, lonely fish is far more likely to nip or hide. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Malabar Danios Good for Beginners?
Often recommended to beginners, but only after the tank is cycled and you can keep a proper school - not three fish in a new setup.
Malabar Danio - frequently asked questions
What size tank do Malabar Danios need?
Malabar Danios need a tank of at least 180 litres (48 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
How many Malabar Danios should I keep together?
Keep a group of at least 6. Malabar Danios are a shoaling species and become stressed, lose their colour, or hide when kept singly or in pairs.
What water parameters do Malabar Danios need?
Keep them at 64-77°F with a pH of 6-8, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
What do Malabar Danios eat?
Malabar Danios are omnivores and aren't fussy eaters. Feed a varied mix of good-quality dry, frozen, and gel foods, and match the food size to their mouths. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Malabar Danios good for beginners?
Yes - Malabar Danios are a good beginner choice once the tank is fully cycled and you can keep a proper group. They are hardy but still need stable water and a school to feel secure.
Common mistakes with Malabar Danios
- Buying fewer than 6 - Malabar Danios need a proper school to feel secure; isolated individuals hide, fail to colour up, or become stressed.
- Underestimating tank size - the minimum footprint is 180 litres (48 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
