Observed during day trip to Tham Pla–Namtok Pha Suea National Park - field # LGN 06-22. I tentatively identified as Neolissochilus sp. On wiki forTham Pla (Tham Pla–Namtok Pha Suea National Park) the resident cyprinid is given as the Soro Brook Carp (=Neolissochilus soroides). I do not know if ichthyologists familiar with the Thai fish fauna agree with that identification.
