Care
The Kansu Loach is known from several tributaries of the Zhu Jiang (Pearl River) system in Guangdong Province, southern China, and from a number of waterways in northern Vietnam. Here, it inhabits clear, cool streams with moderate flow and sandy substrates. The natural habitat should be emulated as closely as possible in the home aquarium by employing powerful filtration and using additional powerheads to create areas of decent current and to oxygenate the water efficiently. Depending on your location, a means of chilling the water may be needed during the warmest parts of the year. As with all botiids, these loaches must only be added to aquariums that are biologically mature. Create a multitude of hiding spots and 'visual barriers' with smooth rounded rocks, cobbles, and pebbles of varying sizes, along with some driftwood. Ensure that the substrate has no sharp edges as these loaches will enjoy digging around the bottom of the tank in their search for titbits of food, and it is important that nothing damages their delicate sensory barbels. Dim lighting is preferable, and a well-covered tank is a must as these loaches are expert jumpers and can escape through the tiniest of openings. As with all botiids, S. robusta fares best with company of its own kind; 3 specimens should be considered the absolute minimum housed together, with 5 or more being much healthier. This will not only allow these fish to form a complex social hierarchy and behave naturally within a shoal, but will also help to spread any territorial behaviour amongst the group. Due to a mildly aggressive temperament, these fish are best housed alongside other fairly robust species, and tankmates could include other temperate botiids, some of the torpedo-shaped nemacheilid loaches, Crossocheilus spp., Garra spp., and some of the medium sized Devario or barb species.
