Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Raios dorsais (total) : 33 - 36; Raios anais : 21 - 23. Caudal fin roundly pointed.

Obligate air-breathing (Ref. 126274); Are broadly adapted species occurring in rivers, lakes, ponds, mountain streams and even brackish water (Ref. 12693). Usually hide under the cover of marginal roots and bogwood. Found in quiet, shaded, clear, flowing water with a silt or gravel substrate (Ref. 6028). Can tolerate very stagnant, poorly oxygenated and turbid water. They also tolerate very foul water (Ref. 1479). Feed largely on insects and crustaceans. A small percentage of fish is also included in the diet. Spawn in shallow water with a silt or gravel substrate. Can tolerate a temperature of 36.5°C.

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Exhibits mouthbrooding. Eggs hatch in the mouth of the male and either parent may keep the brood in its mouth for protection after hatching. Fry have been found to feed on successive batches of eggs laid by the female.

Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00573 - 0.01519), b=3.04 (2.90 - 3.18), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.8 ±0.59 se; based on food items.

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Fec = 933).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).

Categoria de preço (Ref. 80766): Unknown.
