Points about spawning
Many people who keep piranha natteries want to breed them. When they are in the wild, they spawn during the rainy season from April to May. Therefore, when they are allowed to spawn in the aquarium, a half water change will often make them think that the rainy season has arrived and they will spawn.When they mistakenly believe it is time to spawn, the males will be seen breaking in the bottom floor and preparing the spawning beds. If this is successful, females will come to them. Once a pair is formed, the male will begin to rub his body against the bottom of the water while defending his territory. When this movement is observed, the female will lay about 600 sticky eggs. After about 10-14 days after laying the eggs, they begin to hatch. Between the time the eggs are laid and the time they hatch, the male guards the eggs without feeding. Males guarding the eggs are often very temperamental, so care must be taken. It is especially dangerous to mix them with other males, so please keep them separated from the eggs in a separate tank.
