There are two main reasons for the head ulceration of the crane top red goldfish. First, bacterial infection, if the water in the fish tank is not replaced for a long time, it is easy to breed bacteria or parasites, so it is easy to induce this problem. In addition, if the feeding food is unhealthy and pollutes the water, it may also cause this problem.
The second reason is caused by trauma. Fish, even if mild-tempered, can develop a degree of territoriality. If the number of breeding is too large, or mixed with more violent fish, there may be fighting between fish. They gnaw at each other, which may also cause head ulceration. This kind of ulceration is mainly manifested as wound, which needs timely treatment.
If it is caused by bacteria or parasites, first of all, fish out the diseased fish and treat it with salt or potassium permanganate. The water in the original tank also needs to be replaced. After curing, it can be put back to the original tank for breeding, but to increase the frequency of water exchange, it is necessary to replace the water quality in time when it is found that the water quality is getting worse.
If the head ulceration is caused by trauma, you can choose to protect the diseased fish first, and then smear the holes with yellow powder to treat it. After curing, we should also pay attention to maintenance. If the breeding density is very high, it is necessary to replace the large tank or separate tank breeding. If there are very fierce fish in the tank, do not put the crane red goldfish in and mix them.
