Although it is difficult to distinguish between the male and female Angel fish, they can be recognized during breeding time. During breeding, the stomach of the female Angel fish bulges. For breeding, usually angel fishes of 1 year growth are used. Angel fish lays eggs during monsoon and the ideal place for their breeding is a small pond. A peculiar thing about angel fish is monogamous. If we drop a lot of angel fish in a pond or tank for a longer period, it is observed that by the time they are ready to breed, a male and a female angel fish become mates, and their relationship is lifelong. Angel fishes are good parents as they take care of their eggs and fries very well. Such partners are to be dropped into a pond or tank which have plants with big leaves. Angelfish cleans up the leaves where they lay eggs, with their mouth so that the eggs get stuck to the leaves. Both parents take care of the eggs and move their fins in water to create ripples and this helps to keep the eggs always clean. The eggs start to hatch within two days. Usually up to 500 fries are hatched at a single time. Angelfish lay eggs, twice or thrice in a year. The fries start swimming within two days. Angel fish take care of the offspring for about a month.
If the angelfish sense some kind of danger while taking care of eggs or fries, they eat away their offspring. Care should be taken against any disturbances during breeding time. The life of angelfish is a model for everyone. Since angelfish breed twice or thrice a year, commercial farming of angelfish can be a good source of income.
