You can observe the head. The sarcoma of the female fish is lower and less plump, while that of the male fish is tall and plump. Next, observe the gill cover. During the breeding season, the gill cover of male fish has sparse protrusions like star chasers. The pectoral fins of the female fish are short and rounded at the end, while the pectoral fins of the male fish are longer and the tail end is pointed. During the breeding period, there are also stars on the pectoral fins.
The ventarium of the female fish is round and slightly larger, pear-shaped, with the handle end forward, close to the pectoral fin, and slightly protruding outwards; the male fish has a slightly smaller prismatic shape, like a date stone, with sharper ends. , enlarged in the middle, flat and slightly concave. In addition, female fish during the breeding period swim slower and react more slowly; male fish swim more energetically and chase more quickly.
Finally, observe the abdomen of the fish. The abdomen of the female fish is soft, with no obvious hard edges from the abdomen to the anus. During the breeding period, the abdomen is enlarged and rounded; the abdomen of the male fish is hard, with obvious hard edges from the abdomen to the anus. Not swollen.

Extended information:
In terms of water quality and water temperature, Jin Yuanbao prefers fresh fish with a small amount of salt. Salt water, so you can add a little salt during the breeding process. Generally, the pH requirement is between 7.5-8.5, the Gh requirement is between 3-14, and the temperature requirement range is 26-30°C. The origin of Jin Yuanbao is In Central America, southern Mexico and northern Guatemala, they prefer to live in shallow waters of lakes and rivers.
I like to eat some aquatic plants and plants that grow along rivers. I have a relatively docile personality. When I was young, my body color was a bit dull, so the color contrast was not very strong, and the result was not very attractive. But you must be patient and wait.
The adult fish when sexually mature at 15 months is very beautiful, especially during the breeding period, the color contrast on the body is very strong. The head of the mature male Jin Yuanbao will be slightly raised, while the head of the female Jin Yuanbao is smoother and not as bulky as the male.
