Generally, red Arowana turns red in about 2 to 3 years, but this is not necessarily the case. Their hair color will be affected by all aspects. I believe that people who have raised this kind of fish have seen this phenomenon. Their fish have been raised for more than 3 years, but they still have no hair color. At this time, we should consider whether it is because of their own genetic varieties. Some fish don't have hair color because of bad genes.
Generally, the probability of raising the hair color of Arowana for novices is relatively small, because the breeding technology of novices is immature and they will not pay attention to the hair color in the daily feeding process. In addition, the environment in which they grow will also affect their hair color, and arowana that grows in serious pollution will not develop color with high probability.
Second, what red arowana eats helps its hair colorFor mature hair-colored fish, shrimp is generally fed to help its hair color, because shrimp contains astaxanthin, so it has a high probability of hair color. Usually, when red arowana is still a seedling, most of them are fed some high-protein substances, such as bread worms, because high-protein substances can make them grow stronger and provide the basis for their hair color. When the red arowana matures, the food at this time is changed to shrimp, which can make their colors more bright because of astaxanthin.
