পৃষ্ঠীয় কাঁটা (মোট ) : 4; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 6 - 8; পায়ূ কাঁটা : 1; পায়ূর নরম পাখনা্তুন্ড: 8 - 10. Fresh specimens transparent, with large eyes showing the only color, black. Males smaller than females, shorter and more slender. Head naked; body covered with deciduous scales. Scales in longitudinal series 23-24; in transverse series 6. Sides and back of head with few dark or black spots.
Adults occur from the shoreline to depths of at least 12 m. Caught with collapsible Y-shaped push-nets (sakag); also aggregated using a device (abung) wherein the fish comes to rest upon palm leaves and are then harvested using triangular nets (sarap). Sinarapan is a delicacy and of great economic importance to the communities around the lakes. Listed in the Guinness Book of World Records as 'smallest food fish' (Ref. 6472).
Males sometimes mature below 1 cm; females a little over 1.1 cm. The eggs are pelagic. Upon hatching, the young swims at the surface for a short while, then settles at the bottom.
