Etymology: Potamothrissa: Greek, potamos = river + Greek, thrissa, -es = shad (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical; 7°N - 5°S
Africa: widespread in the Congo River basin in Central African Republic (Ref. 45441) and Democratic Republic of the Congo (Ref. 4910, 41585, 42510). Reports from Lake Mweru (Ref. 361) and Zambia (Ref. 52959) unconfirmed in Ref. 93833.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm SL male/unsexed; (Ref. 188)
soft rays: 16 - 27. Body slender. Pre-pelvic scutes fairly strongly keeled, beginning under or just before pectoral fin base, 11 to 13 + 10 to 12. Snout pointed. Lower jaw not projecting, included in upper when mouth closed, deepest at mid-point of jaw, with small saw-like teeth on either side; pre-maxillae with rather peg-like teeth; maxilla very slender; second supra-maxilla very small.
Occurs in rivers and lakes, apparently in both still and running water. The distribution of this species suggests that it tolerates a wide variety of water conditions.
