[[ Genus Pseudolaguvia ]]

Pseudolaguvia is not a diverse group, and this diversity is confined to a small area (between the Ganges and Sittang River drainages). Therefore, it is not surprising that most of the species are sympatric, and in a few cases, even syntopic. The underlying mechanism for this occurrence is yet to be investigated. While it is known that fish form heterospecific shoals in order to better avoid predators or to increase foraging efficiency (Pitcher, 1986), this seems unlikely in species of Pseudolaguvia , given their cryptic habits and the fact that the catfishes are armed with spines. It is also possible that the fish are not actively shoaling, but have merely aggregated in areas providing the most cover.
