Arowana to eat small fish is best, but both small fish and loach can be fed to Arowana, because loach and small fish are live baits, and they are rich in protein and fat, so they can be fed to Arowana. However, the nutrient content of small fish is richer, and loach is easy to secrete mucus, which will destroy the water quality and make the water quality worse. In addition, the feeding amount should not be too large, otherwise the arowana will turn black, so if the breeder wants to feed it as a staple food, it is best to choose small fish.
2. What is the best for Arowana to eatIt is best for Arowana to eat some live bait, because live bait can not only arouse their appetite and interest in predation, but also increase their activity and reduce fat accumulation and indigestion. Breeders can usually feed them some live fish, live shrimp, loach, tadpoles, water fleas, water lice, water earthworms and so on. These live baits are rich in nutrients, easy to digest, and will not cause enteritis and other diseases.
However, live bait is easy to carry parasites and bacteria, so breeders need to soak them in potassium permanganate solution for about 10 minutes before feeding. This can effectively kill the parasites and bacteria carried by the live bait and avoid the infection of Arowana.
