簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 9-10; 臀鰭軟條: 7 - 8; 脊椎骨: 40 - 43. Diagnosis: pelvic fin origin at level of anterior base of dorsal fin; preorbital stripe present; caudal peduncle depth 6.9-11% of SL; dorsal precaudal fin fold not reaching base of dorsal fin; 8-9 pectoral fin rays; 7 pelvic fin rays; 2 supernumerary rays in anal fin; 8 dorsal fin pterygiophores; 9+9 principal caudal fin rays; cephalic lateral line canals and supraorbital bone present; parasphenoid wide, with foramina for internal carotid arteries; neural spine of 2nd vertebra short and wide, only the length of its vertebral centrum and different from subsequent neural spines (Ref. 57474).
Maximum TL was recorded at 4.1 cm (Ref. 3566). Occurs on several substrates from fine mud to rough gravel and plant material; almost never buries into the substrate (Ref. 57474). Feeds on plankton (Ref. 57474, 91322) and phytoplankton (Ref. 91322). Reproduction likely takes place during the rainy season (August to September) (Ref. 57474) at high water levels in floodplains, brooks or rice fields (Ref. 91276, 91322).
鑽進沙子裡面。 最大體長TL記錄為 4.1 公分。 (參考文獻 3566)
