Serpenticobitis is a genus of small Southeast Asian stream loaches, recorded in the atlas from Laos, Thailand, Myanmar, and Vietnam. As the name suggests, its body plan is notably elongate and serpentine compared with more familiar hillstream or kuhli-type loaches, a slender build shared with several other stream-loach lineages in the region's fast, rocky headwaters. Atlas species are tiny, running 1.5–2.5 in.
This is a genus of scientific rather than hobby interest - it rarely if ever appears in the aquarium trade, and detailed natural-history data on diet, behaviour, and breeding are sparse in the sources available here. Conservation status reflects that same gap: the brief's tally is 3 Not Evaluated, meaning none of the atlas species in this genus has yet received a formal IUCN assessment.
