Pseudomystus is a genus of catfishes (order Siluriformes) of the family Bagridae.

[2] P. carnosus, P. fumosus and P. moeschii are hypothesized to form a monophyletic group.

[2] The genus is distributed in Thailand, Vietnam, Malaysia, and Indonesia, on Java, Sumatra, and Borneo, with only P. siamensis and P. bomboides known from north of the Thai Peninsula.

[2] Many Pseudomystus species are beautiful fishes with colour patterns of striking contrast, with light bands and/or blotches on a dark background on the body and fins, with the pattern reversed on some fins in some species.

They are highly adaptable and can live in almost any water condition (though extremes should be avoided).
