Researchers examined specimens collected from several locations throughout the Zambezi River system. Earlier field observations had revealed considerable differences in body shape, skin texture, and colour patterns among fishes previously identified as Chiloglanis neumanni. The new study confirms that several of these populations represent separate species. Named after the Shire River, this species is characterised by its relatively long barbels around the mouth. It also has ridge-shaped skin projections, comparatively large eyes, and longer dorsal- and pectoral-fin spines than some closely related species. These anatomical features help distinguish it from other Chiloglanis species occurring in the same river system (Mutizwa TI et al.). Aquarium Care: Good oxygenated water from a power filter. Sand or gravel substrate with smooth rocks or pebbles. Their dorsal and pectoral fins are sharp and can cause wounds if not handled carefully. Sexual Differences: Usually in the form of a different shaped caudal fin. Diet: Mouth and dentition suggest that it is a bottom feeder and algal grazer. In the aquarium feed algae, fly larvae foods, bloodworm, and flake food. Etymology: The specific name shirensis refers to the Shire River system where this species is found.
