The body color is generally brownish with a lighter belly. The fins are relatively large, with the dorsal and pectoral fins having strong, serrated spines.

The Phalacronotus bleekeri is found in freshwater environments such as rivers, streams, and floodplain lakes. It prefers slow-moving or still waters with a muddy or sandy bottom. The species is widely distributed in Southeast Asia, with populations in the Mekong and Chao Phraya basins, the Malay Peninsula, and Sumatra.

Diet and Behavior

As a nocturnal species, the Phalacronotus bleekeri is most active during the night. It is a bottom-dwelling species that feeds primarily on small invertebrates, including insects, crustaceans, and mollusks. It uses its barbels to detect food in the substrate.

Conservation Status

The conservation status of the Phalacronotus bleekeri is not well-studied. However, like many freshwater species in Southeast Asia, it is likely threatened by habitat loss and degradation due to human activities such as deforestation, pollution, and overfishing.

In the Aquarium
