If the small fish are fed too much, the small fish may get enteritis, and feeding too much will not finish the food, and it will also affect the water quality in the fish tank. The owner should change the water in the fish tank frequently to keep the water clean.

What you need to pay attention to when feeding small fish:

1. It is best to adjust the water temperature in the fish tank to a constant temperature to maintain a temperature that the small fish likes, because the water temperature is The key to raising small fish. For small fry, a difference of about 1-2 degrees in water temperature may endanger their lives. For adult fish, as long as the water temperature is controlled within a certain range, the fish can grow healthily.

2. Generally, an increase of 1-2 degrees is most suitable for the growth of small fish at the temperature suitable for adult fish. For example, the suitable temperature for adult fish is 24-25 degrees, then the suitable temperature for fry is about 26-27 degrees. Because at this temperature, they will feel warm and their appetite will become better. After the frequency of activity increases, the growth rate will also accelerate.

3. Frequent changes in water temperature can also cause sudden death of small fry. In particular, owners should pay special attention when changing the water in the fish tank. The constitution of small fish is weak. If the water temperature differs by more than 2 degrees, the small fish will become sick or die because they cannot adapt.
