Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical; 18°C - 23°C (Ref. 2060)
South America: southern tributaries of the Mirim Lagoon.
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.8, range 4 - 4 cm
Max length : 5.5 cm SL male/unsexed; (Ref. 80013)
soft rays: 9. Fins colorless. The ground color of the body is olive gray and the flanks show six to eight dark, fine lines or dotted longitudinal stripes; the underside is light. Males are significantly more slender and smaller than females. Both sexes exhibit almost the same coloration. Unfertilized females have an orange-colored spot on the anal fin, situated either on the right or the left (Ref. 26130).
Occurs in shallow water. Viviparous (Ref. 26130), found along with the livebearing Cnesterodon decemmaculatus in waters with heavy algal growth. Genital opening in the female asymmetrical.
Gestation period usually lasts six weeks. Produces 10 to 20 (rarely up to 40) young.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00625 - 0.02534), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=10-60; gestation usually lasts 6 weeks; tm=1; K=1.04-2.46).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (13 of 100).
