Can angelfish breed?
Of course you can! But it requires some skill.
Freshwater angelfish are relatively easy to breed: you'll see paired angelfish clean a flat surface before laying eggs. Once the eggs hatch, the parents usually care for the "fry".
Breeding marine angelfish is more complex and requires specialized equipment and extensive experience.

Like any pet, angelfish may present some challenges in their care:
Diseases : Freshwater angelfish are prone to fin rot, while saltwater angelfish are prone to white spot disease.
Territorial disputes : They may chase other fish, so choosing the right aquarium companions is very important.
Water quality issues : Angelfish are very sensitive to sudden changes in pH and temperature.
