Batasio

About

Found in Thailand, this obscure small catfish, Batasio tigrinus, shares its genus name as its common name. A hint at how rarely it turns up in the hobby outside of specialist circles. It belongs to a group of laterally compressed catfishes distinguished by prominent sensory pores on the head and a narrow chin region, giving them a somewhat angular, purposeful look. The tiger-striped patterning that inspired the name makes it one of the more visually interesting members of its genus. Despite being labeled aggressive and territorial, it is not quite the bruiser that label might suggest. It holds its own but should not be housed with anything large enough to intimidate or bully it. A school of similarly sized, peaceful cyprinids works well in the upper and mid-water columns, while smaller akysid or sisorid catfishes and balitorid loaches from appropriate genera make reasonable bottom-level companions. Like many catfishes from fast-moving Asian streams, it appreciates good water movement and a well-oxygenated setup. Breeding has been documented in related species, with large cool-water changes apparently triggering spawning behavior and eggs hatching within roughly two days. This is a species for the keeper who enjoys digging into lesser-known Asian catfishes and is comfortable with intermediate-level care demands.
