who is the lebiasina-sem-listras
The unstriped lebiasina is a small freshwater fish of the family Lebiasinidae, reaching 16 cm. It occurs west of the Andes, in northern Ecuador and southern Colombia. It lives near the bottom of small, shallow forest streams, in tropical water at 22 to 26 °C. Like other lebiasinas, it gulps air at the surface when oxygen runs low in the water. It has commercial fishing and is sold for aquariums. For rod-and-reel anglers it is not a featured species.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the lebiasina-sem-listras; in the meantime, see the similar species.
identification
Small, elongated fish of the family Lebiasinidae, reaching 16 cm. Its flank has no dark longitudinal band and shows a series of round spots, which helps separate it from its relatives: Lebiasina bimaculata, from Ecuador and Peru, has two spots on the body, and Lebiasina multimaculata, from southwestern Colombia, has many small spots. Its range, northern Ecuador and southern Colombia west of the Andes, also helps.
