Under natural conditions, after the male and female arowana lay eggs, the male fish hatch all fertilized eggs in his mouth, which is very difficult for artificial reproduction. Arowana belongs to tropical freshwater fish and is carnivorous. From young fish to adult fish, animals must be fed with bait, preferably live food. The water temperature should be between 25℃ and 28℃, and the PH value of water should be between 6.5 and 7.5. When changing seasons, we should pay special attention to raising fish tanks and cooling them. Young fish with a body length of about 10 cm feed on crustaceans such as shrimp, Daphnia, Chironomid and aquatic insects. You can also feed krill, frozen fish, sausages, fish rolls, artificial feed, etc. If you are trained, you can accept more kinds of food.
