Glugea

Glugea is a rare fish disease. It's the first time I have seen it with my own eyes. The disease looks like bubbles on the body of a fish. Once burst, it will spread the disease to other fishes. So, it's best to separate infected fish from the main tank. There is no cure for the infected fish but I don't have the heart to terminate the life of any fish myself. I have no idea why my Kuhli Loach is infected by this disease. Hopefully, the disease has not spread to other fishes.

Here's my poor Kuhli Loach that is suffering from Glugea. I hope it will die as soon as possible to avoid suffering.
