Surrounding landscape has semi-evergreen forest, plantations, and agricultural crops (mainly corn, cabbage and tomato). Water temperature was 17°C, air temperature 20.5°C, pH 7.7, DO 6.5 mg/l, and conductivity 20 μS. Averaged stream width 4 meters, and water depth 40-60 cm. Specimens were collected during the daylight by electro-fishing. Other species collected at the type locality were Schistura breviceps, Schistura maejotigrina, Oreoglanis siamensis, Scaphiodonichthys burmanicus, Opsarius pulchellus, Garra cambodgiensis, Puntius brevis, Puntius stoliczkanus, Monopterus albus, Channa gachua and Devario sp.
