Among males, the dorsal and anal fins are elongated. ReproductionThese fish start to spawn when they are 10 cm long. The sticky eggs are deposited in tight rows. The female lays between 200 and 500 eggs on average, sometimes up to 2,000. Before the fry swim freely, the parents may carry them in their mouths. DietBlue acaras eat mosquito larvae, other invertebrates, plankton and plants. They are omnivorous. PredatorsTheir enemies are other fish, birds and humans. HabitatThey live in fresh, stagnant water, close to the shoreline, where they hide among the grass. Some of the places in which they are found are Panama, Colombia, Venezuela, Trinidad and Tobago. Ecology, behaviourThese are probably the sturdiest of all cichlids. Essentially peaceful, they are very popular aquarium fish. They can become aggressive toward others in their species, however, during mating and when defending their territory. Before spawning, the male and female grasp each other by the jaw, to test each other's strength. After selecting a spawning site, the male and female clean it with their mouths.
