Yaoshania

The panda loach, Yaoshania pachychilus, is a balitorid loach from headwater streams draining the Dayao Mountain in Guangxi, southern China. The name comes from the black-and-white-striped juvenile pattern, which fades in older fish, so only young fish tend to be traded, sometimes labelled 'panda goby'. It needs clean, well-oxygenated, fast-flowing water, and though often marketed for them it is not suitable for tiny 'nano' aquaria.
