1, stop to feed: If tropical fish catches a cold, want to stop to feed it above all. Sick fish's own appetite will decrease, or even do not eat, so feeding is meaningless, and food into the water as residual bait, but also a certain degree of pollution to the water quality, so need to stop feeding, until recovery to continue feeding.
2. Temperature control: The main reason for catching a cold is that the temperature has changed too much. In order to prevent the aggravation of the disease and to recover as soon as possible, attention should be paid to controlling the water temperature. The temperature of raising tropical fish should be at least above 20 ℃, generally 22-26 ℃ is better, but the daily increase should not be too large, up to 2 ℃ a day.
3. Medication: If the cold is serious, it needs to be treated with medication. Prepare a separate fish tank, pour in the original tank water, and add a little baking soda, put the fish in it to soak, can promote metabolism, enhance its vitality, can also add a certain amount of sea salt, can also play a bactericidal effect.
