After spawning, the females often are removed to a separate aquarium as the male may become aggressive toward her. The male protects the eggs and fry, but normally is removed after they become free-swimming. After hatching, frequent water changes, especially during the third week, are used to ensure the health of the fry, as this is when the labyrinth organ is developing. Three spot gourami
