White frost on goldfish may mean that the goldfish has leukocoat disease, which is due to acidophilic dinoflagellates entering the body of the goldfish. Generally, when goldfish suffer from leukocoatism, they will have symptoms such as anorexia, sluggishness, and inactivity. If there is a white frost-like substance on the goldfish, it means that the goldfish is in a dying state.

Tip:

When a white frosty substance is found on a goldfish, the owner must first isolate the goldfish and raise it alone to prevent the disease from spreading and infecting other goldfish. Then, the goldfish's body should be washed repeatedly with salt water for disinfection, which is also beneficial to the health of the goldfish. Recovery, if discovered in time, some antibacterial drugs can also be used.
