Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 10 - 12; Raggi anali molli: 9 - 10; Vertebre: 16 - 17. Males have red dorsal and caudal fins, sometimes with red anal fins, and lack a black blotch on the dorsal fin base. Males sometimes have a red dorsum. Have the following combination of characters: eye distinctly bulging above dorsal surface of head; dorsal fin rays 10-12 (mode 10); anal fin rays 9-10 (mode 10); pectoral fin rays 15-16 (mode 15); dorsal fin base length 9.3-11.7% SL; anal fin base length 7.5-9.5% SL (Ref. 39332).
Body shape (shape guide): short and / or deep; Cross section: circular.
Specimens typically caught along bank vegetation in large rivers. The specimen from Sambas were obtained amongst submerged bank vegetation. The water was murky brown, with pH about 6.0. Syntopic species include Rasbora tornieri, R. bankanensis, Doryichthys deokhatoides, Brachygobius doriae and Dermogenys sp. (Ref. 39332).
