Ecology
Freshwater; benthopelagic. Tropical; 24°C - 28°C (Ref. 13371)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.5 cm SL male/unsexed; (Ref. 38376)
Lateral line incomplete.
South America: Upper Solimões, Mana and Approuague River basins.
Frequently found in waters with slow current or the counter current zones of small creeks with clear water and sandy bottom. It occupies the upstream portion of rivers before a waterfall. Its capture in great numbers suggest a gregarious behavior (Ref. 12225). Its reproduction in captivity has not been reported (Ref. 27188). Maximum length 5.0 SL (Ref. 12225).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00888 (-0.21703 - 0.23479), b=3.24 (3.12 - 3.36), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 2.9 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
