Morphology | Morphometrics
soft rays: 11. Distinguished from congeners of Aphanius and other species of Valenciidae and Fundulidae in Europe by the following characters: males have dark grey caudal fin, with a distinct submarginal bar and 4-5 vertical rows of hyaline dots sometimes organized into regular bars; males possess 14-17 dark grey bars on a silvery background, bars irregularly shaped and set, often connected; females have a few large black spots on side, usually organized into two rows, one on middle of flank, one level with pectoral base; 24-26 scales in lateral line series on body; pectoral fin with 9-10 rays; and anal fin usually with 9 rays (Ref. 59043).
Inhabits lagoons, tidal canals and small, shallow coastal streams, with water fresh to hypersaline and with silt bottom. Omnivorous, feeding on zooplankton, small insects, vegetal matter and detritus. Freshwater populations are threatened due to the introduction of Gambusia holbrooki and Fundulus heteroclitus (Ref. 59043).
Individuals born in spring mature at 3-4 months and spawn the same year; those born later spawn the following year (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00435 - 0.02094), b=3.23 (3.05 - 3.41), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Assuming tm<1).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
