Short description Morphology | Morphometrics

This species is distinguished from its congeners in having the following characters: maxilla short 0.70-0.77 times in anal fin base; head large 2.7-2.9 times in SL; male with 6-7 diffused dark bars along sides, covering only upper half of body; female with an irregular ocellus on dorsal fin, its black spot half-moon shaped, smaller than a pupil; eye 1-1.2 times in anal fin base; postdorsal-postanal 0.9-1.1 times in caudal peduncle length; anal fin usually smaller than its congeners, 3-3.9 times in head length; teeth absent on 4th ceratobranchial; dorsal fin inserted behind pelvic origin; nuptial males violaceous blue (Ref. 26729).

Biology     Glossary (e.g. epibenthic)

The springs at Ojo Charco Azul (= Barreno) are part of the Bolsón de Sandia complex, at 1600 m above sea level, and at the foot of Sierra Montelongo Pedregoso. The area is semiarid, with cacti other succulents; a densely woody area of cedar around the springs, except on the eastern side. Formerly the water was crystal clear at 19-20°C, but recently after depletion, the water is brown. Aquatic vegetation includes Ceratophyllum, Potamogeton, Typha, Eleocharis, Lemna, Utricularia, Scirpus, and Chara; crayfish Cambarellus sp. was observed. The bottom is loamy or muddy (Ref. 26729). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00448 - 0.02337), b=3.21 (3.02 - 3.40), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.4 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 (12 of 100) .
