Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 1; Dorsale zachte stralen (totaal): 3-5; Wervels: 29 - 30. Can be diagnosed from all congeners by the following characters: reduced mesethmoid, wider than long, (mesethmoid length 12.1-15% HL; width 17.2-19% HL); lower jaw slightly protruding beyond upper; nasal ossified, tubular, not sutured to mesethmoid; third nuchal plate reduced; small prevomer, with short rostro-lateral process; elongate postcleithral process, sometimes as long as head length; ribs 5-6; and vertebrae, 29-30 (except Tatia galaxias, rarely having 30). Deferent duct externally elongate and anal-fin base swollen, with a thick secretory pouch in mature males. Can be further differentiated by the following combination of restricted characters: females with genital papilla; anal fin of mature males bearing rays with uncurved segments; and caudal fin lobes with about the same length in both adult females and males. Other distinguishing characters include whitish ground color pattern with brown spots, pattern mottled or with irregular stripes; ventral surface of head covered with short brown irregular stripes; body with a characteristic dark band along lateral line; and a small adult size of less than 4 cm SL (Ref. 79512).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

This is typically associated with blackwater environment, mainly in rivers. In central Amazon, it occurs both in black and clear waters but only in dense vegetation where there is minimal light. Field data suggest that this fish inhabits water with low pH, low conductivity and low level of dissolved oxygen. Reaches sexual maturity above 2.8 cm SL (Ref. 79512).
