if you want to keep small fish alive, you must first pay attention to changing water. The purpose of changing water is to maintain water quality, but not too frequently in order to make the water clear, at least once every 3-5 days, if the water quality is well maintained, it can be changed once a week. In addition, the amount of water changed each time should also be controlled, not more than one third of the total amount of water, generally about one quarter or one fifth.
small fish must be frequent, so as to develop rapidly and enhance their physical fitness. It should be noted that according to the different types of fish, the choice of feed is also different, herbivorous fish like to eat plants, carnivorous fish to feed shrimp, snails, mussels and so on. However, feeding must not be too much, feeding too much is easy to cause enteritis, but also bad water.
of small fish requires a higher temperature, compared with adult fish, generally 1-2 degrees higher. If the temperature is relatively low, the fish's appetite will become less vigorous, and they do not like to swim, and they will even die after a long time. It is better to use a heating rod to control the temperature in case the temperature changes greatly in a day.
usually small fish prefer an environment with high dissolved oxygen, so it's better to oxygenate the fish tank. The method of oxygenation is very simple. Prepare an oxygen pump, put it into the fish tank, and turn it on for 24 hours. If you feel that electricity is consumed, you can also use it intermittently for two hours in the morning and two hours in the afternoon.
