General Description
The Porthole Bagrid, scientifically known as Hemibagrus Punctatus, is a species within the Bagridae family. It is typically a small fish, reaching a maximum size of around 23.0cm. This species has a unique coloration pattern with dark spots arranged in vertical columns on its flanks. It is primarily found in the Cauvery river system in southern India, and its status in the wild is currently uncertain, with the IUCN listing it as Critically Endangered, possibly extinct. The etymology of its scientific name, Hemibagrus, derives from the Greek "hemi," meaning 'half,' and the generic name Bagrus, while "punctatus" comes from the Latin "punctatum," meaning 'punctuated,' in reference to its color pattern.
Aquarium Setup
Porthole Bagrids are likely to thrive in aquariums with dim lighting and ample refuges, such as driftwood, large rocks, or plastic piping. To accommodate their needs, an extensive filtration system and regular water changes would be essential for their care. The ideal water conditions for these fish include a pH range of 6.0-7.0, a temperature between 20-27°C, and a hardness of 36-268ppm.
Behaviour
This species of fish is known to exhibit aggressive territorial behavior, making them incompatible with most other fish species, except in exceptionally large public installations where they can coexist.
Feeding and Diet
Porthole Bagrids are believed to feed on smaller fish and invertebrates in their natural habitat. In captivity, they can be fed a diet that does not require live fish, with 1-2 meals per week usually sufficient for adult individuals.
Reproduction & Dimorphism
Details about the reproduction of Hemibagrus Punctatus are currently unrecorded. In terms of dimorphism, this species can be distinguished by various physical characteristics, including its unique color patterns and body proportions when compared to congeners.
Habitat and Distribution
The primary habitat of Hemibagrus Punctatus is the Cauvery river system in southern India. It has also been documented in man-made reservoirs within the Cauvery basin. Recorded localities of this species include the Kabini, Bhadra, and Moyar tributary systems. However, due to its critically endangered status, its exact distribution and population in the wild are uncertain.
