Nematabramis Borneensis

Datasheet

General Description

Nematabramis Borneensis, a species within the Cyprinidae family under the classification order Cypriniformes, is characterized by barbels longer than the head but not extending beyond the pectoral-fin base. The body is relatively slender, with a depth that fits 3.6-4.2 times in standard length (SL), and the head is relatively long, with a length that fits 3.8-4.1 times in SL. This species has 8 branched dorsal-fin rays, 13-16 branched anal-fin rays, and 8 scale rows between the dorsal-fin origin and anal-fin origin. It bears a dark lateral stripe on the body, distinguishing it from similar species like N. alestes by its longer barbels.

Aquarium Setup

The Nematabramis Borneensis typically requires an aquarium setup that mimics its natural habitat, including swiftly-flowing tributary streams, pools, lakes, and degraded swamps. The water parameters should be maintained within the recommended range (see table) to ensure the well-being and comfort of the fish. Decorate the aquarium with plants, rocks, and driftwood to provide hiding spots and territories for the fish, creating a conducive environment for their natural behaviors.

Behaviour

Known for their lively and active nature, Nematabramis Borneensis are social fish that prefer shoaling with conspecifics or other peaceful species. They exhibit typical danio behavior, displaying fast movements and exploring all levels of the aquarium. These fish are not known to be aggressive but should be housed with species that can withstand their energetic nature.

Feeding and Diet

In their natural habitat, Nematabramis Borneensis feed on a varied diet consisting of small invertebrates, insects, and plant matter. In an aquarium setting, they should be offered a balanced diet of high-quality flake food, pellets, live or frozen brine shrimp, bloodworms, and vegetable matter. Regular feeding schedules should be maintained to ensure their nutritional needs are met.

Reproduction & Dimorphism

The reproductive behavior of Nematabramis Borneensis in an aquarium setting involves scatter spawning, where the female scatters the eggs among plants. The eggs are adhesive and will stick to surfaces. The males will fertilize the eggs, and both parents should be removed after spawning to prevent them from eating the eggs. Sexual dimorphism in this species is not prominently visible, making it challenging to differentiate between males and females based on physical characteristics alone.

Habitat and Distribution

Endemic to the Malaysian state of Sabah in northern Borneo, Nematabramis Borneensis is primarily found in a variety of habitat types, ranging from swiftly-flowing tributary streams to pools, lakes, and degraded swamps. The species' type locality is in the Kota Belud District, specifically Kota Belud.
