Max length : 14.0 cm TL macho/indeterminado; (Ref. 5217); common length : 12.0 cm TL macho/indeterminado; (Ref. 5217)
Espinhos dorsais (total) : 0; Espinhos anais: 0; Raios anais : 23 - 27. Snout sharply pointed but short, less than eye diameter; maxilla long, tip pointed, reaching almost to gill opening; gill cover canals of panamensis-type. Anal fin moderate, its origin below or just before midpoint of dorsal fin base. A silver stripe along flank, less than eye diameter.
Occurs in shallow coastal waters, sometimes in large schools, and also in mangrove-lined lagoons in turbid water. On the southern coast of Margarita Island, they appear mainly in February to May at 5-7 cm SL, while larger individuals occur throughout the year in the interior of lagoons. More data needed on food and breeding.
