Épines dorsales (Total) : 15 - 17; Rayons mous dorsaux (Total) : 13 - 15; Épines anales: 3; Rayons mous anaux: 10 - 11. Diagnosis: body rather elevated (body depth 46.9-51.6% SL) (Ref. 53405). Head profile rounded (Ref. 81260). Outer teeth on jaws bicuspid (Ref. 53405), gracile (Ref. 81260) and spatulated (Ref. 53405, 81260). Lower pharyngeal jaw teeth relatively small and narrow near posterior border of bone, forming an almost felt-like covering (Ref. 81260). Micro-gillrakers present; adults (> 150 mm) with a series of dark blotches in the middle of the flanks (sometimes body entirely blackish) (Ref. 53405, 81260). Juveniles with 7-9 large vertical bands (Ref. 53405). Ventral scales with central red spot; 12 or more rakers on lower limb of first gill arch (Ref. 81260).
Body shape (shape guide): fusiform / normal.

Biologie     Glossaire (ex. epibenthic)

Live in still or flowing waters in rocky or mud-bottom areas (Ref. 44894). Occur in warm springs and mud-bottomed to sand-bottomed canals (Ref. 5723). Clearly prefers a herbivorous diet, including algae, higher plants and parts of cassava, but also accepts insects and shrimps (along with their eggs) (Ref. 52307). Consume plant matter. Reache sexual maturity at 10-15 centimeters length. Parents prepare nest site on logs, leaves and other debris. Prolific species (Ref. 52307). The eggs (600-3300 per female) are guarded by the parents and hatch in 1-3 days. Larvae need 6-8 additional days to develop before they can swim freely (Ref. 52307). Parental care of the brood continues until the fish are about (1.5 cm, Ref. 52307) 2.5-3.0 centimeters (Ref. 44894). Occurs in mixed groups composed of individuals of varying size/age, along with individuals of other species (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307). Maximum size was recorded at 39.4 cm TL (Ref. 40637).

Estimations basées sur des modèles

Indice de diversité phylogénétique (Réf. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.01361 - 0.01845), b=3.00 (2.96 - 3.04), in cm total length, based on LWR estimates for this species (Ref. 93245).
Niveau trophique (Réf. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Résilience (Réf. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Fec = 2,000).
Vulnérabilité de la pêche (Ref. 59153):  Low to moderate vulnerability (28 of 100). 🛈
Nutriments (Ref. 124155):  Calcium = 195 [105, 334] mg/100g; Iron = 1.41 [0.84, 2.69] mg/100g; Protein = 18.6 [17.1, 20.0] %; Omega3 = 0.247 [0.139, 0.509] g/100g; Selenium = 47.5 [28.7, 82.9] μg/100g; VitaminA = 15.7 [4.6, 38.4] μg/100g; Zinc = 1.8 [1.3, 2.7] mg/100g (wet weight);
