What is chalk body?

Chalk body refers to a condition that is characterized by the accumulation of calcium carbonate crystals in the skin cells. These crystals cause the skin to become hard, rough, and appear chalky white in color. Chalk body is often seen in aquarium fish, such as goldfish and koi, and is commonly referred to as "lateral line disease."

Chalk body can occur due to various reasons, including poor water quality, stress, and viral or bacterial infections. It can also be a result of genetic factors. The condition is not life-threatening, but it can affect the overall health of the fish and make them more susceptible to further infections.

Treatment for chalk body involves addressing the underlying cause and improving water quality. This may include frequent water changes, adding water conditioners and aquarium salt, and treating any infections.

Prevention is the best approach to avoid chalk body. This can be achieved by ensuring proper water quality, providing a balanced diet, and avoiding crowded aquariums. Regular monitoring of the fish's health and behavior can also help detect any potential issues early on.
