There are almost too many fish species, and no aquatic species has the same method of distinguishing males and females that retains these distinctions. Naturally, in the way of distinguishing male and female fish, there are certain connections and similar methods between different aquarium species. So, how should we identify the gender of fish? How to identify male and female fish?
First of all, you can distinguish male and female fish based on their first personality. Generally speaking, female fish are larger than male fish, with swollen abdomen and slightly protruding reproductive pores. Male fish mostly show variations in fins and snouts, such as fin extensions, but they are not all the same, and some fish have no obvious male-female characteristics.
Secondly, many fish undergo color variation during the reproductive season, with male fish showing bright colors. Some fish have pearl stars on their bodies, especially on the snout and pectoral fins. In some fish, pearl stars also appear on many parts of the entire head and anal fins.
