Facultative air-breathing (Ref. 126274); Restricted to forested areas and small, shallow, slow flowing silted streams with leaf debris and thick marginal vegetation. Stays close to the substrate and is very seldom found in unshaded waters. Feeds on fish fry, plankton and insect larvae. Bubble nest builder.
Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Male builds the bubble nest. Spawns 100 to 200 whitish eggs in batches in the course of a period between 1 to 12 hours. Eggs sink to the bottom and both parents pick them up and place them in the nest, usually built under a submerged leaf, after fertilization. Eggs hatch in 2 days. Male solely guards the eggs and young until they reach free-swimming stage and are independent one week after spawning.
