Neon Tetra Disease General Description |
As the disease progresses, affected muscle tissue begins to turn white, generally starting within the color band and areas along the spine. As additional muscle tissue is affected, the pale coloration expands. Damage to the muscles can cause curvature or deformation of the spine, which may cause the fish to have difficulty in swimming. It is not unusual for the body of the fish to have a lumpy appearance as the cysts deform the muscles.
This disease was originally described in Neon Tetras, but can affect many other species of fish (i.e. danios). In Neons, one of the early signs of this disease is a loss of the red colour, and difficulty swimming Note that there is a so-called "false neon disease", which is bacterial, and shows very similar symptoms.

Neon Tetra Disease Treatments |
|
None, separate or euthanize diseased fish. I recommend using clove oil & vodka. There is no known cure. To ensure all fish are not lost, remove diseased fish from the tank. Some species, such as Angelfish, may live for quite some time. However, they should be separated from uninfected fish to avoid spreading the disease.

|
Neon Tetra Disease Prevention |
|
The best prevention is to avoid purchasing sick fish, and to maintain high water. Carefully observe the suppliers fish. Do not purchase any fish from tanks where there are sick, dying, or dead fish present. Fish that do not school, or hang apart from the others, should be suspect.
