This fish has sale in fresh market. I don't asked shopkeeper about a place that catched it but I think this fish came from somewhere in central part of Thailand.
Slightly less than an inch in length, has black wings. Unfortunately, it was covered with dirt and cobwebs so some distinguishing features were hidden.
Ukuran 5,8 cm. Saya jumpai pada sungai berukuran sedang, beraliran tenang, berjarak 9 km dari pesisir, ketinggin 38 m
