for the bloodshot fish? There are many reasons for the bloodshot fish. It may be because the water quality is not very good, or because the temperature difference between day and night is too large, or because of bacterial infection. For different situations, treatment methods are not the same, if only the problem of water quality, appropriate water can be changed, if the temperature difference is too large, it is necessary to maintain a constant temperature first, and then slowly warming. Bacterial infections need to be treated with drugs, usually yellow powder or potassium permanganate.
bloodshot fish? 1. Change water: bloodshot fish shows that the water quality is not very good, so it is necessary to change water for fish at the first time. At this time, the change of water is different from usual, it needs to be changed more frequently, usually every other day, about a quarter of each time, so as to improve the water quality as soon as possible, so that the fish can recover slowly.
2. Heat up: After changing the water, the next step is to heat up. Warming has both advantages and disadvantages. The advantage is that it can promote the metabolism of fish, so that it can discharge harmful substances as soon as possible, and at the same time, it can improve the vitality of fish. The disadvantage is that it will increase the reproduction rate of bacteria, so salt needs to be added to the water.
3. Salt: The function of salt is to increase the osmotic pressure of the water body, thereby reducing the entry of water, which can also hinder the invasion of bacteria. It should be noted that the concentration of salt should not be too high, otherwise it will affect the health of fish, or even lead to their death. It is usually kept below five thousandths.
