Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 23 - 31.

Adults inhabit lower reaches of streams and rivers, also seagrass beds in estuaries and other shallow inshore habitats (Ref. 43081, 44894). Occur in mangrove estuaries and tidal creeks (Ref. 44894). Males exhibit parental care by incubating and guarding the eggs in their brood pouch (Ref. 43081). Ovoviviparous (Ref. 205).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Monogamous mating is observed as both obligate and genetic (Ref. 52884). Female deposits eggs on the ventral surface of the male's tail, where they are incubated for several weeks (Ref. 2847).

Estimates based on models

Preferred temperature (Ref. 115969): 24.5 - 29, mean 27.9 (based on 1098 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00037 (0.00016 - 0.00085), b=3.18 (2.99 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
