If the angelfish is in the juvenile stage, then generally speaking, it is impossible to distinguish between male and female, and the difference between male and female is relatively small. After about 9 or 10 months, they reach maturity, and it's easier to distinguish between males and females.
First of all, they can be distinguished from their appearance, and sometimes the differences can be more obvious. For example, their forehead, the forehead of the male fish is more developed, full, the forehead of the female fish is relatively smooth; Then the reproductive organs, male reproductive organs are slender and relatively sharp, female reproductive organs are thick and round; Then there are their fins, the fins of male fish are generally longer than those of female fish. In addition, it can also be judged from their body characteristics. For angelfish of the same age, the male is generally larger than the female. In addition, if they are in the breeding season, then the distinction between male and female is relatively simple, those abdominal swelling phenomenon is the female fish.
Male and female angelfish can be raised together. Angelfish's character is more gentle, but also more quiet, generally speaking, will not conflict. Moreover, their requirements for the surrounding environment are not too high, for example, they can grow in weak acid, neutral and weak alkaline water. Moreover, there is no big difference between the habits and characteristics of male and female angelfish, which is easier to control. As long as they are provided with enough space and food in the process of breeding, they will not fight with each other.
