How to raise the little arowana?

1. Culture environment

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.

About 15 cm of crayfish can be fed with normal bread worms and shrimps (preferably without shrimp swords), or 1.5 cm of small fish. 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.

3. Density

If the culture body length of 20 cm arowana, in 5 square meters of aquarium can be 15, 15 square meters of 30, 40 square meters of 40, 200 square meters of 120. It can be seen that the density should be reduced as much as possible.

4. Change water

Change water at least 20% Mel 30% per week, and ammonia content should not exceed 0.1 parts per million (mg/l). Don't make the temperature and pH change suddenly.

If you want arowana to grow well, you must have more than 4-8 hours of light, preferably in daylight, so that the color of the arowana will be better.
