Hampala Bimaculata

Datasheet

General Description

The Hampala bimaculata, a species belonging to the Cyprinidae family, is largely unrecognized in the aquarium trade due to its adult size, making it unsuitable as an aquarium fish. Within the genus Hampala, consisting of seven species, the H. macrolepidota stands out as the largest and most commonly observed in the trade, contrasting with the rare sightings of H. dispar. Differentiating features include the distinct color patterns such as dark vertical bands and caudal-fin stripes, with juveniles of the two species exhibiting similar markings but with varying intensities.

Aquarium Setup

The Hampala bimaculata requires a setup mimicking its natural habitat, a preference for clear, fast-flowing river waters. Ideal aquarium conditions would involve a substrate of sand or gravel, well-oxygenated water, and ample space for swimming. For detailed aquarium setup requirements, refer to the table below.

Behaviour

This species typically favors riverine environments with moderate to strong water currents. In the wild, they are known to coexist with various fish species such as Barbonymus balleroides and Garra borneensis. Understanding their natural behavior is crucial for providing a suitable environment in captivity.

Feeding and Diet

The feeding habits of Hampala bimaculata revolve around omnivorous tendencies, displaying a diverse diet consisting of both plant matter and small aquatic organisms. In captivity, a varied diet including live or frozen foods rich in protein and occasional plant matter is essential for their nutritional needs.

Reproduction & Dimorphism

Information on the specific reproductive behaviors of the Hampala bimaculata is limited. Unlike some closely related species, distinguishing between male and female individuals based on physical characteristics may be challenging. Further research may shed light on the reproductive strategies and potential dimorphic features of this species.

Habitat and Distribution

Endemic to the island of Borneo, the Hampala bimaculata has been documented in various regions including the Malaysian states of Sarawak and Sabah, the Indonesian province of East Kalimantan, and Brunei Darussalam. Its habitat preference includes clear, running waters with substrates of sand, gravel, rock, or mud, commonly found in tropical forest environments as observed in sympatric settings with other fish species.
