1. Generally, the daily feeding frequency of tropical fish is more in the juvenile stage than in the adult stage. Generally, young tropical fish are fed three times a day, and adult fish are fed twice, which is also related to the feeding habits of fish. In addition, tropical fish are usually fed four times a day in factory farming, which grows faster, but it is easy to get sick.

2, eat less and eat more meals. For example, small fish such as lamprey and guppies are suitable for feeding with less food and more meals, but not too much at a time, because these small fish have fast digestion, short nitrification system, lively and active, and most of them are omnivorous. They are in the predation stage almost all day in nature, and they can replenish energy as long as they meet food. If the feeding interval is too long to affect its growth rate, the growth period of small fish is generally short, and most of them have grown up in three to four months, and food will be short.

3. Time quantitative method. Most fish can be fed this way once a day in the morning, at noon and at night. The feeding amount is the largest at noon and the least at night. When cultivating outdoors, the feeding amount should be reduced when the temperature is low, the air pressure is low, it is cloudy or rainy. Feeding fish regularly and quantitatively is beneficial to the digestion and absorption of food.
