Care
The striped barb is a larger relative of the five-banded barb and a schooling fish that should be kept in a group of at least 8–10. In a good-sized group it is less nervous and shows better colour. Because it grows to about 10 cm, give it a tank with a base of at least 120 × 45 cm (around 162 litres). It comes from peat swamps and blackwater streams, so a heavily planted or forest-stream style tank suits it: a soft substrate, dim lighting, roots, branches and leaf litter, with plants such as Java fern (Microsorum), Java moss (Taxiphyllum) and Cryptocoryne. Leave open swimming space along the front. Keep it in soft, slightly acidic to neutral water: about 20–25 °C, pH 5–7 and 1–10 dGH. Young fish show four dark vertical bars like other Desmopuntius, but by about 3–4 cm long these change into five or six bold horizontal black stripes on a golden body, which makes adults easy to recognise. Similar striped species include D. gemellus and D. trifasciatus, which are sometimes mixed up with it in the trade. Adult males are slightly smaller, slimmer and more colourful than females. The species was moved from Puntius into Desmopuntius in 2013, and it is still often sold as Puntius johorensis. It is listed as Least Concern by the IUCN (assessed 2019).

Diet
In the wild it forages on algae, diatoms, detritus, small insects, worms, crustaceans and zooplankton. In the aquarium offer a varied mix of good dried flakes or granules that include some plant matter, plus small live and frozen foods such as bloodworm, Daphnia and Artemia.
Breeding
An egg-scatterer with no parental care that spawns readily when well conditioned. Set up a separate, dimly lit spawning tank with a mesh base (so eggs fall out of reach of the adults) or plenty of fine-leaved plants or spawning mops, with soft, slightly acidic water at the warm end of the range. Add a well-fed pair or small group and remove them once eggs are seen. In the wild it is reported to spawn in very shallow water. The eggs hatch in 24–36 hours and the fry swim freely 3–4 days later. Start them on infusoria-sized foods, then microworm and newly hatched brine shrimp.
Compatibility and tank mates
A peaceful fish for a South-East Asian community of similar-sized, soft-water species: other Desmopuntius such as the five-banded barb, rasboras, small loaches and gentle gouramis. Avoid very boisterous or aggressive fish, and very small fish that could be outcompeted at feeding time.
