The over-backed Arowana means that all the six rows of scales on their bodies turn golden yellow, so that they can be called over-backed Arowana. The scales in the sixth row of them happen to be on the back, and not all the scales on the back of Arowana will turn golden yellow. Only properly raised Arowana can become over-backed Arowana. It is difficult for young Arowana to judge whether they are over-backed, because the backs of their young Arowana are all black, and only when they are adults can they judge whether they are over-backed Arowana by the scale color of their backs.
2. How to raise over-backed Arowana1. Feed more color-enhancing feed: If you want Arowana to become over-backed Arowana, you should feed them more color-enhancing food. For example, small fish, shrimp, centipede, etc., these foods are beneficial to their hair color, and the nutrients in the food are abundant, so they can be fed to Arowana for a long time.
2, increase light: Arowana can receive more sunshine when it is in the wild, and it is necessary to ensure that they live in sufficient sunshine when they are raised artificially. If you can't receive too much sunlight, it is recommended to install aquarium lamps, which can also replace natural light.
3. Keep the environment stable: In the process of breeding at ordinary times, it is necessary to ensure the stability of their living environment and minimize the fluctuation of water temperature and water quality, so that they can develop better.
