Is my fish male or female？

　　
I just saw an article saying that the mother fish will hold back eggs![kelian][kelian][kelian]!How to divide male and female? Shunde District, Foshan City, Guangdong Province
========How did the fish friends of the Xianglong Aquatic Alliance comment==
龙巧儿 鱼友说：雄龙有含卵育儿的重任，所以相对雌龙，其头部较宽厚健硕，正面看，两额角与两唇底角基本呈上下同宽的长方形，雌龙呈An inverted triangle with a wide top and a narrow bottom. The male larynx has a protruding throat bag, and there is a dark black halo on the expansion and contraction parts on both sides; the pectoral fin stem is thick in color;The female dragon does the opposite.
