Looks how to spot one
Small scaled cyprinid (barb)
A small, neatly built barb with a gently arched back. A dark line runs along each side from the snout to the base of the tail, and the scales above it are finely edged in darker tones, giving a net-like look. Males are slimmer and smaller, and turn a rich cherry red, especially when ready to spawn. Females are fuller-bodied and a softer tan with a reddish wash.234
Personality what they are like
Calm, gentle and a little shy when kept in small numbers. In a proper group it becomes much bolder and more active, and males put on colourful displays for the females. Unlike some of its barb relatives it is not a fin-nipper, so it fits well into a peaceful community tank.234
Daily activity how busy a day looks
Moderately active, cruising the middle and lower water in loose groups. It is happiest with open swimming room alongside thick planting where it can weave and hide.24
Grooming and care the hands-on bits
Easy to keep. Regular partial water changes and a varied diet keep it lively and colourful. Colours look their best in a well-planted tank with a dark substrate and subdued lighting.23
Home where they are happiest
Aim for a tank with a base of at least 60 x 30 cm (about 54 litres); hobby guides range from about 40 litres for a group of six up to 100 litres or more for a larger school. Temperature roughly 20 to 27 C (23 to 27 C is the commonly quoted tropical range), pH 6.0 to 8.0 and hardness about 2 to 20 dGH. Recreate its shaded forest streams with plenty of plants, leaf litter, a sandy or fine substrate and gentle flow.2134
Food basics what goes in the bowl
An omnivore. Wild fish graze on algae, diatoms and organic debris and also pick off small insects, worms and crustaceans. In the aquarium offer good small flakes or granules, plus live or frozen treats such as bloodworm, daphnia and brine shrimp, and some plant-based food like spirulina.123
Company who they like around
A schooling fish that should live in a group of at least 5 to 10, ideally with both sexes so males show their best colour. It mixes well with other peaceful fish such as small tetras, livebearers, rainbowfish, gouramis, catfish and loaches.213
The story where it all began
The cherry barb comes only from the rainforest streams of south-western Sri Lanka, where it lives in shallow, shaded, slow-moving water over silt and fallen leaves. It was scientifically described in 1929 by Deraniyagala, and its species name appears to come from a local Sri Lankan name for the fish. The genus name Puntius traces back to a Bengali word for small carp-like fishes. Its colour and easy-going nature made it a fixture of the aquarium hobby, and today it ranks among the most common small cyprinids sold. Sri Lanka no longer allows wild specimens to be exported, so almost all cherry barbs in shops are bred on fish farms, which has also produced ornamental forms such as albino, super red and long-fin. Outside its homeland, populations have also become established in parts of Colombia, Mexico and Panama after being introduced. In the wild it is listed as Vulnerable by the IUCN.1243
Fun facts for the dinner table
- 1
It is found naturally nowhere in the world except a small stretch of Sri Lanka, from the Kelani to the Nilwala river basins.1
- 2
Males deepen to their brightest cherry red when they are ready to spawn and when females are around.2
- 3
A single spawning can scatter around 200 eggs among plants near the water's edge.1
- 4
Its eggs hatch in just one to two days, and the fry are swimming freely within about two days.1
- 5
The genus name Puntius comes from 'pungti', a Bengali word for small carp-like fish.2
- 6
Sri Lanka prohibits the export of wild cherry barbs, so the ones in shops are almost all farm-bred.2
- 7
Unlike its famously nippy cousin the tiger barb, the cherry barb is known for leaving other fishes' fins alone.3

Owner questions the things everyone asks
How often should I feed my Cherry Barb?
Feed small amounts once or twice a day. Furry Diary's starting plan is to feed daily, offering only what they can eat in a couple of minutes. Overfeeding can harm water quality, so keep portions tiny.1 Pet Wiki plan
What does a Cherry Barb eat, and what should it never eat?
Cherry Barbs are omnivores and enjoy good small flakes or granules, plus live or frozen treats like bloodworm, daphnia, and brine shrimp, along with plant-based food like spirulina. Never feed them anything that could foul the water or that is not designed for small tropical fish, and always check with a vet or good breeder for specific concerns.123
How much space does a Cherry Barb need?
A tank with a base of at least 60 x 30 cm (about 54 litres) is recommended, though hobby guides range from about 40 litres for a group of six up to 100 litres or more for a larger school. More space is always better for their active swimming and schooling behavior.2134
What temperature, light or water does a Cherry Barb need?
Keep the water temperature between 20 and 27°C, with pH 6.0 to 8.0 and hardness about 2 to 20 dGH. They prefer subdued lighting and a well-planted tank with gentle flow, mimicking their shaded forest stream habitat.2134
How often should I clean a Cherry Barb's home?
Furry Diary's starting plan suggests a weekly 25% water change, along with weekly glass cleaning and water testing. Rinse the filter in old tank water once a month, never tap water, to keep the environment healthy. Pet Wiki plan
Can a Cherry Barb live with others?
Yes, Cherry Barbs are peaceful schooling fish that should live in a group of at least 5 to 10, ideally with both sexes. They mix well with other peaceful fish like small tetras, livebearers, rainbowfish, gouramis, catfish, and loaches.213
How long does a Cherry Barb live?
Cherry Barbs typically live between 5 and 7 years with proper care. A stable, clean tank and a varied diet help them reach their full lifespan.4
Can I handle a Cherry Barb?
It is best not to handle Cherry Barbs, as they are delicate fish that can be stressed or injured by handling. Enjoy watching them swim and display in their tank instead.
