The small fish fed to Arowana must first be kept fresh, because feeding them with stale live bait may cause gastrointestinal diseases. Before feeding, it is necessary to remove the scales, head and tail of small fish, so as to prevent them from scratching the internal organs of silver arowana. After removing their heads and tails, they need to be soaked in salt water or potassium permanganate solution for 10-20 minutes, and then frozen in the refrigerator, which can kill bacteria and parasites in small fish. If you want to feed the silver arowana, you need to take the small fish out of the refrigerator first, and then feed it to the silver arowana after it is completely thawed.

Silver arowana prefers animal feed. Besides small fish, breeders can also feed them some small shrimps, such as metapenaeus ensis, abundant shrimp and river shrimp. However, before feeding, it is also necessary to remove the head and shell, soak and freeze. You can also feed some freeze-dried feeds, such as red worms, yellow mealworms, bread worms, etc., or feed some beef, mutton, chicken, animal viscera, etc.

Although they prefer animal feed, it is recommended that breeders regularly feed them with some plant feed to ensure their nutritional balance. If the breeder has enough time, he can break and mix the plant feed and animal feed, which can also avoid the picky eaters of Arowana.
