Lateral Line Corrosion (Hole in the head Disease)

© Winston Vaughan Schoenfeld

This article is a continuation of the current series of diseases to fresh and saltwater fish. This article will discuss a disease known as "Lateral Line Disease," or more commonly, "Hole in the head disease." It is a sickness which effects marine species, in particular, the following:

• angelfish
• tangs
• damsels
• grouper
• butterflyfish

The main symptom of this disease is a lack of color or pigment, mainly around the eyes. The fish may seem to be otherwise healthy (except for a slight decrease in eating), and will continue to swim around the aquarium normally. In addition, small portions around the eyes and the lateral sensory line of the body can appear to be rotting away. The fish may also seem to have a bit of a whitish film on its exterior due to an increased slime buildup.

To date, the cause of this disease is not known. There have been a number of speculations about its origin, but none have been proven. It has been found that a treatment with a diet high in vitamin C will have beneficial effects, and can heal a diseased fish. As a result, many have speculated that this disease has to do with a lack of vitamin C. The best solutions to treating this disease is to first check the environment. Measure chemical levels in the aquarium, and make sure that the aquarium has proper pH and temperature. Next, you should start a diet for the fish which is rich in vitamin C. Exposure to sunlight or increased lighting has also been shown to aid in the recovery of the fish.

If left untreated, the fish will soon become increasingly effected by the disease, and eventually will become highly susceptible to other bacterial infections, which may ultimately lead to death. The key is early detection and treatment. The earlier the fish is treated, the greater it's chance to survive. Remember, increase the vitamin C in the diet of the fish, and try to expose the aquarium to direct sunlight, or increased lighting periods.
