Environment / Climate / Range
Freshwater; pelagic. Tropical; 7°N - 3°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.7 cm SL male/unsexed; (Ref. 188)
soft rays: 16 - 27. Body slender. Scutes strongly keeled, beginning under pectoral fin base, 10 + 10 or 11. Snout rather acute. Lower jaw slightly projecting, with small teeth; pre-maxillae with a single row of small teeth; maxilla slender, its blade a little over 3 times as long as deep, upper edge slightly ridged; second supra-maxilla slender, spatulate, with distinct anterior shaft.
Africa: restricted to the region of Lake Tumba and the Ruki River, also the Congo River at Mbandaka and its nearby tributary, the Busira as far up as Bokungu on the Tshuapa branch.
Occurs in rivers and lakes, apparently in both still and running water. It seems to occur in rather acid waters.
