General Description
The Bagrichthys Obscurus, commonly known as the "lancer," is a species belonging to the Bagridae family within the order Siluriformes. It is distinguishable by its relatively small and narrow mouth, reduced oral dentition, slender body, and uniformly brown coloration. The species possesses an extended dorsal spine, which is the origin of its vernacular name.
Aquarium Setup
For optimal habitat replication, a tank of at least 270 litres is recommended for the Bagrichthys Obscurus. The aquarium should be dimly lit to accommodate its nocturnal nature. Providing hiding spots like clay flowerpots, plastic piping, and driftwood is essential. While plants are not obligatory, they aid in reducing light exposure and offering coverage. It is advised to create distinct territories if multiple specimens are kept together, and avoid strong water flow. Placement of the heater should be fish-friendly, preventing them from resting against it.
Behaviour
The Bagrichthys Obscurus is a peaceful species that thrives alongside dither fish such as larger rasboras, medium-sized barbs, or the glass catfish. While territorial towards other benthic species, especially conspecifics, it is recommended to keep a single male with three or more females to minimize aggression and enhance long-term success.
Feeding and Diet
In the wild, the Bagrichthys Obscurus feeds on small benthic animals and organic detritus. In captivity, they readily accept various aquarium foods, including live and frozen fare like Artemia, Tubifex, and bloodworms. High-quality sinking dried products with Spirulina or other vegetable content should be regularly provided.
Reproduction & Dimorphism
Reproduction of Bagrichthys Obscurus remains unrecorded in captivity. In their natural habitat, adults migrate to flooded riparian zones during the wet season to spawn. Sexually, males exhibit a pointed genital papilla and longer barbels, while mature females tend to be slightly larger in body size.
Habitat and Distribution
Typically found in large, turbid rivers with muddy substrates and slow flow, the Bagrichthys Obscurus migrates to flooded riparian areas during the wet season. This species was initially described in northeastern Thailand, particularly from the Chao Phraya, Bang Pakong, and Mekong watersheds. Records also exist from Cambodia and Vietnam, with possible presence in Laos.
