Description of life cycle and mating behavior Spawning occurs during the wet season. Adult males guard and aerate the hachlings and young temporarily. Adult males develop vascular filaments on their paired fins which function either as auxillary to respiration so that they can breathe air without leaving the nest or the fin filaments permit the emission of aerially obtained oxygen in to the nest water, causing the oxygenation of the water surrounding the eggs (Ref. 111170). The function of the filaments is much debatable as of the present.
