Fish tanks for arowana culture should be equipped with filters, aerators, lighting and other equipment. Arowana needs weakly acidic to neutral water for survival, and soft water is required for hardness. The pH value is between 6.57.5 and the DH value is 3-12. The water temperature is 24-28 degrees Celsius.
two。 Feed
Young fish less than 12 cm have just begun to eat raw bait, then you can feed white bread worms, shrimp (be sure to turn around and tail, it is best to peel shrimp balls so as not to hurt their intestines and stomach), blood worms and other more palatable bait. Eat less and eat more and feed four times a day.

At this time, the arowana grows rapidly and eats an astonishing amount. The feeding times and amount can be increased appropriately. In addition, when we feed the arowana, we must pay attention to one thing: we should be full for about 7 minutes each time, and we should pay attention to the diversity of food, otherwise it will easily lead to bulimia or anorexia.
