Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 5.0 - 6.0; dH range: 0.10000000149012 - 10; non-migratory. Tropical; 23°C - 27°C (Ref. 42575)
South America: Amazon River basin, in Ecuador, Peru, Colombia and Brazil, in tributaries of the rivers Ucayali, Marañón, Solimões and Amazon from about the Pachitea River on the Ucayali River to about Gurupá; upper Mamoré River in Bolivia, and Madre de Dios River drainage in Peru; Essequibo River drainage in Guyana; Amapá Grande River in Amapá, Brazil.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 36377)
In forest creeks and sandy river shores, often near fallen leaves or among plants. Young are all females; at about 8 months of age one female changes into a dominant male (Ref. 42575).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00785 - 0.03846), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tm<1).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
