Description of life cycle and mating behavior | Thrives in seasonal rainwater pools. Spawns throughout the short breeding period until the pool dries up and all fish die except their drought-resistant eggs. Eggs go through a dry period of many weeks. When rain comes and pool fills, most of the eggs begin to develop and hatch within hours. Fry grow very fast. In only 6 to 8 weeks they are sexually mature and start breeding (Ref. 7062). In aquaria, males showed aggressive behavior toward each other. Females were being pushed down to the substratum by the males as a prelude to spawning. |
