The difference between male and female rainbow sharks is not too big, so it is difficult to distinguish them from each other, so we often choose to distinguish them from their appearance. Specifically, they mainly have the following ways to distinguish:
1. From the appearance, the body of the male rainbow shark looks smaller, while the body of the female rainbow shark is larger.
2. From the abdominal posture, after sexual maturity, the female rainbow shark's abdomen looks more bloated, while the male rainbow shark is more slender.
3. From the body color, the tail color of male rainbow shark is mainly golden red, while the tail color of female rainbow shark is mainly orange red.
4. In terms of personality, the male rainbow shark is more irritable, while the female rainbow shark is more gentle.
Male and female rainbow sharks can be raised together. Rainbow sharks follow the principle of "monogamy", so in normal life, male and female can be mixed together, which can also allow them to reproduce naturally. But in that proces of mixed culture, attention should be paid to the culture density, and a male fish and a female fish can be taken out for separate reproduction in the breed period, otherwise, fighting phenomenon can easily occur between the male fish and the male fish, and casualties and losses can be cause.
