the fish to be frightened, most likely because of environmental discomfort, in which case the fish tend to swim around. In view of this situation, the best solution is to rest, do not continue to stimulate it, so do not feed and change water to the fish, the temperature should also be maintained to avoid excessive temperature difference between day and night.
of new fish If the fish has been raised in the tank, when the new fish is put into the tank, the original fish may be frightened and run around in the tank. Therefore, it is better to isolate the new fish first, put the isolation board in the tank to avoid it meeting other fish, and then get the isolation board after a period of adaptation.
for fish farming requires change of water. Long-term non-change of water will lead to deterioration of water quality, and fish will run around when they feel uncomfortable. But again, if you change the water too often, or if you change a lot of water each time, the new water will stimulate the fish and cause it to run around. Therefore, we must pay attention to the water change cycle, usually once a week, each time a quarter of the total amount can be changed.
When the water temperature in the fish tank changes and the temperature difference between day and night is relatively large, the fish will also be frightened. Therefore, we must pay attention to temperature control at ordinary times, we can use heating rods to keep constant temperature, temperature control above 20 C, so that fish are not easy to go wrong.
