Issue
See Géry (1977: 446) for identification key.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; pH range: 6.0 - 7.2; dH range: 8 - 20. Tropical; 23°C - 28°C (Ref. 12468)
South America: Guianas coastal rivers and the Amazon River basin.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 27188)
Abundant and very ubiquitous; found throughout the length of rivers (Ref. 12225). Prefers slow moving waters of small creeks where the substrate can be very variable (sand, rocks, plant debris) (Ref. 12225).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00754 - 0.02645), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.50 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
