Causes of Neon Tetra Disease

An organism called Pleistophora hyphessobryconis causes Neon Tetra Disease.

The disease is communicated throughout the fish in the aquarium once fish consume the dead bodies of other fish in the tank or live food servings such as Tubifex, which can act as an intermediary carrier of the disease.

Once the fish in your tank consume the deceased particles, parasitic spores enter the body of the fish and begin to consume the healthy host.

As the disease progresses, cysts begin to show on the infected hosts and they begin to deteriorate from the inside out.

This is most commonly evidenced by a pale white color on the infected fish.

Key Indicator of Neon Tetra Disease

The first key indicator of Neon Tetra Disease in your aquarium is restlessness of infected fish.

An aquarist can do this by maintaining high quality water levels with regular cleaning, especially after the initial outbreak.

In addition, one should also be very strict in purchasing his or her fish to identify the above symptoms in pet stores before you purchase and bring them to your home aquarium.
