Overview

The lined barb is a small, peaceful schooling barb for the middle of a mature blackwater tank. It is a step up from the easiest barbs.

Did you know

The lined barb is sometimes confused in shops with other striped barbs, such as Desmopuntius johorensis. Its thin, continuous stripes, rather than blotches or bars, set it apart from most look-alikes.

Caring for the lined barb

Keep lined barbs in a group of at least eight, in a tank of 20 gal (75 L) or more. They need stable, soft water in a mature blackwater tank rather than a brand new setup.

Give them soft, acidic water at 73 to 81°F (23 to 27°C) and a pH of 5.0 to 6.5. If your tap water is hard, they are a poor choice. Alder cones, leaf litter and gentle filtration through peat help hold the low pH. In a proper blackwater tank, they are hardy and long-lived.

Feed small flakes and micropellets, plus frozen daphnia, cyclops and bloodworm. Lined barbs are peaceful and safe in a community tank. Breeding them is hard.

Good to know

The lined barb belongs to the family Cyprinidae and carries several thin dark stripes along a slender, pale body. It was once placed in Puntius as Puntius lineatus. A 2013 reclassification of the old barb group moved it to the genus Striuntius.

In the wild

The lined barb lives in soft, tea-colored blackwater across the Malay Peninsula, Sumatra and Borneo, in streams, swamps and peat forests. These are shaded, acidic waters stained by decaying leaves, with very little dissolved mineral content.
