Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13 - 15; Dorsal soft rays (total): 9 - 12; Anal spines: 3; Anal soft rays: 7 - 9; Vertebrae: 25 - 27. Diagnosis: 14-18 gill rakers on first gill arch; no large spots on flanks (Ref. 81260). 4-6 bands or 2 rows of dark blotches and short horizontal lines usually visible when stressed (Ref. 50577, 81260). Relatively robust (body depth 26.7-38.2%, mean 34.4% SL); lachrymal depth less than 21% HL (Ref. 81260). No iridescence on cheek, operculum and flanks (Ref. 50577).

Prefers smaller rivers and creeks; normally found near the banks where plenty of hiding spots are available; diet consists primarily of small particles, preferably plant matter, although shrimp eggs and insect larvae are also taken (Ref. 52307). Monogamous (Ref. 52307), pair-bonding, ovophilic, biparental mouthbrooding species (Ref. 52307, 81260).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

In aquaria, a monogamous, pair-bonding, biparental ovophilic mouth brooder. Eggs are deposited on hard substrate or on leaves and incubated by the female for the first 2 or 3 days; afterwhich incubation may be done by both male and female (but mainly by female) (Ref. 50577).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
