Description
Paralaubuca harmandi is a small to medium‑sized cyprinid fish. Reported maximum total lengths are in the range of 10–15 cm, although precise size limits vary among populations. The species possesses the typical cyprinid body plan: a laterally compressed, elongated body, a terminal mouth, and cycloid scales. Its coloration is generally silvery with a faint dorsal stripe; detailed patterning may differ regionally.
Distribution and Habitat
The species is native to mainland Southeast Asia. Documented occurrences include the Mekong River basin and its tributaries, extending through Laos, Thailand, Cambodia, and Vietnam. It inhabits freshwater riverine habitats, preferring mid‑water to surface zones in moderately flowing stretches. Seasonal migrations for spawning have been reported in related Paralaubuca species, though specific patterns for P. harmandi are not well documented.
Ecology
Paralaubuca harmandi is primarily planktivorous, feeding on zooplankton and small aquatic insects. It forms part of the local food web, serving as prey for larger predatory fish and aquatic birds.
Conservation Status
According to the International Union for Conservation of Nature (IUCN) Red List, Paralaubuca harmandi is classified as Least Concern. The assessment notes that the species has a relatively wide distribution and no major widespread threats have been identified. However, localized pressures such as habitat modification, dam construction, and water pollution could affect regional populations.
