Why does the angelfish eat her eggs?

Angelfish may eat their eggs for several reasons, including stress, perceived threats, or a lack of experience. In some cases, the parents may consume the eggs to prevent them from being eaten by predators or to ensure that they can focus on caring for any surviving fry. Additionally, if the eggs are not fertilized or show signs of disease, the angelfish may instinctively eat them to maintain the health of their environment.
