Looks how to spot one

Deep-bodied, laterally compressed scaled cyprinid

A fairly large, deep-bodied danio with a silvery body. Each flank carries a light-coloured stripe that breaks into sections, and unlike many danios it has no barbels on the upper jaw. Females are rounder, a little larger and less colourful than males.1

Colourssilveryblue-greylight interrupted stripesyellowish fins1

Personality what they are like

Active and busy but not aggressive. Its energy can unsettle very shy fish, so it fits best with robust tankmates of a similar size.1

Daily activity how busy a day looks

A fast, energetic swimmer that needs a long tank with plenty of open water.1

Grooming and care the hands-on bits

Keep the water clean and moving with regular partial changes. It jumps well, so a secure lid is needed.1

Home where they are happiest

A tank with a base of at least 120 x 45 cm (about 243 litres). Temperature 15-26 °C, pH 6.0-8.0, hardness 2-15 °H (FishBase 5-19 °H). Open swimming space with some plants and rocks works well.12

Food basics what goes in the bowl

An omnivore that mainly eats insects in the wild, plus algae, worms and small crustaceans. Offer quality dried food with live or frozen bloodworm and Artemia.12

Company who they like around

Keep at least 8-10 together. Choose robust, similar-sized community fish as companions.1

The story where it all began

Francis Hamilton described this fish in 1822 from the rivers of Bengal, making it one of the earliest danios known to science. It is now kept by aquarists, and the trade also offers a short-bodied form and an albino form.231
