1. How to divide Arowana into male and female 1. Look at the size: The size of male and female Arowana is different, and breeders can judge male and female by their size. When males and females grow in the same environment, the males will be wider and longer in size and the females will be narrower and longer in size.
2. Look at the head type: The heads of male and female arowana are also different. The heads of male fish will be larger and those of female fish will be smaller. Breeders can compare male and female together, which can be easily distinguished.
3. Look at the oral cavity: The oral cavity of male and female arowana is also different. After arowana lays eggs, male fish need to put their eggs in their mouths to hatch, and they will release the small fish only after the hatching is successful. Female fish don't need to hatch their eggs, so their mouths will be smaller.
4, look at pectoral fins: To distinguish male and female arowana, you can judge by the color of their pelvic fins. The pectoral fins of male fish will be darker and the pectoral fins of female fish will be lighter.
2. Can male and female Arowana be raised togetherIt is not recommended to raise male and female Arowana together. First of all, they are relatively large in size, and if they are raised together, there may be insufficient space. Secondly, their character is fierce, and if they are raised together, they may fight. Their aggressiveness and attack power are relatively strong. Once there is a fight, the injury will be more serious. Finally, they have strict requirements on water temperature and water quality. If male and female are raised together, it may lead to great changes in the environment.
