Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical; 7°N - 8°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm SL male/unsexed; (Ref. 188)
soft rays: 16 - 27. Body slender. Pre-pelvic scutes not strongly keeled, beginning under or just behind base of last pectoral fin ray, 7 to 10 + 10 to 12. Snout rounded; lower jaw not projecting, exactly meeting tip of upper when mouth closed, deepest at mid-point, with small saw-like teeth on each side; pre-maxillae with small teeth pointing downward; maxilla very slender; second supra-maxilla very small
