the fish food at the bottom of the fish tank? The fish food at the bottom of the fish tank can be cleaned when the water is changed. Prepare a tube, put one end to the bottom of the fish tank, the other end outside the fish tank, but lower than the bottom of the fish tank, suck from the outside of the tube, through the siphon method to pump out the water, at the same time, the fish food at the bottom of the tank is also discharged. It should be noted that too much water should not be pumped out to clean the fish food, and too much water change is also harmful to the fish.
should we pay attention to when feeding fish at ordinary times? 1. Feed replacement: Fish can not be fed with one kind of feed for a long time, which will not only make the nutrition of fish unbalanced, but also cause them to be picky eaters and not eat other things. It is better to change the feed regularly with a variety of food to ensure the healthy growth of fish.
2. Food control: Many fish have no stomach, so they will eat all the time, but feeding too much will lead to water pollution, and even cause enteritis and other diseases, so we need to control the amount of food. After each feeding, ensure that the fish are finished within 3-5 minutes, and those that are not finished must be fished out and cleaned up in time.
3. Feeding time: The fish are usually fed during the day, unless the nocturnal fish are raised in time. It is usually fed after 9 o'clock in the morning and before 4 o'clock in the afternoon. In winter, as the temperature drops, the feeding time should be adjusted in the morning and evening, after 10 o'clock in the morning and at 3 o'clock in the afternoon at the latest.
