1. Reason: The temperature becomes very low in winter and early spring. If the koi is raised outdoors, the koi is likely to catch a cold.
2. Treatment method: At this time, the koi needs to be moved to a warm place for maintenance. During curing, keep the temperature between 20 degrees and 26 degrees. If outdoor maintenance is necessary, the water temperature can be maintained by deepening the water level line, because when the water level line is relatively high, the low water temperature in the tank will not be too low.
1. Reason: When maintaining the koi, if the water temperature is not well controlled, the water temperature will rise and fall, and the koi will easily catch a cold.
2. Treatment method: Stop feeding the koi immediately, and at the same time, keep the water temperature of the koi at about 25 degrees. After the koi cold is cured, it will be maintained normally.
1. Reason: The water temperature is too low in autumn and winter. If water is injected into the koi fish tank frequently, the water temperature balance of the fish tank will be broken, and the koi fish will catch a cold.
2. Treatment: At this time, it is necessary to fish out the koi with a cold from the fish tank to avoid infecting other koi. During the quarantine period, no feeding is allowed. This situation generally does not require medication, keep the water temperature between 20 degrees and 26 degrees on the line. It should be noted that during the isolation period, the maintenance water needs to use old water, not new water. Conservation with old water is helpful for the recovery of Koi.
