Desmopuntius Pentazona

Datasheet

General Description

The Five-Banded Barb, scientifically known as Desmopuntius Pentazona, is a rare species in the aquarium trade, with similar-looking variants often mistakenly sold as the closely-related D. hexazona. The distinguishing feature of D. pentazona is a small dark marking near the base of the dorsal fin, absent in D. hexazona. Belonging to the Cyprinidae family, this small fish exhibits unique 4-6 bar color patterns in juveniles, transforming into stripes with age. Adult males are slimmer and display more intense coloring compared to females. It can reach a maximum size of 5.5cm and is native to the Borneo region in Southeast Asia.

Aquarium Setup

Ideal for heavily planted tanks or forest stream-type setups, the Five-Banded Barb thrives in soft substrate, dim lighting, and an environment resembling sluggish waters with roots, branches, and leaf litter. Suitable tankmates include comparably-sized peaceful Southeast Asian fishes like cyprinids, cobitids, and certain anabantoids. A group of 8-10 individuals is recommended to prevent skittishness and enhance natural behavior display.

Behaviour

This species is a schooling fish by nature and tends to display its best colors when kept in groups of at least 8-10 specimens. It is best suited for a peaceful community tank with non-aggressive tankmates, as boisterous companions might outcompete it for food. The males compete for female attention within the group, showcasing vibrant colors.

Feeding and Diet

The Five-Banded Barb is primarily a micropredator, feeding on small insects, worms, crustaceans, and zooplankton in the wild. In the aquarium, a varied diet is essential for optimal coloration and breeding condition. It readily accepts dried foods but should be supplemented with daily feedings of small live or frozen fare like Daphnia and Artemia.

Reproduction & Dimorphism

These barbs are egg-scattering spawners that exhibit no parental care. To maximize breeding, a separate breeding tank with dim lighting and appropriate substrate should be set up. Controlled spawning with one or two pairs or in a larger group with specific water conditions can yield successful results. Fry hatch within 24-36 hours and should be fed infusoria-grade food initially.

Habitat and Distribution

Found in peat swamps, blackwater streams, and still waters with submerged vegetation, the Five-Banded Barb inhabits regions with brown, acidic water and minimal dissolved minerals. Endemic to northwest Borneo, this species is closely related to D. hexazona, which occurs in southern Borneo and the Malay Peninsula. Its typical habitat includes substrates littered with leaves, branches, and occasional aquatic plants from genera like Cryptocoryne and Barcalaya.
