Neon Tetra Disease is a mysterious disease that strikes mainly neon tetras, but other fishes are also susceptible to it. The online opinion is that there is no cure, some even suggest euthanizing the poor tetra to avoid it spreading.
Neon Tetra Disease Signs
The signs of neon tetra disease include some of the following classic symptoms:
- Loss of color in a patch of skin
- Fin rot
- Curved spine in advanced cases
Our neon tetra exhibited two of the classic signs (white patch and loss of color near the head), and fin rot near the tail. For more pictures and graphics of the symptoms, see the video below.
Neon Tetra Disease Cure (Melafix?)
We seem to have stumbled upon a cure for neon tetra disease using Melafix. Melafix is a herbal fish medicine based on tea tree oil, and is targeted at bacterial infections of fish.
After one dose of Melafix, and over 9 days, our neon tetra has shown a dramatic improvement (as seen in video below). The white patch of loss of color is gone, and the fin rot near the tail is gone as well. In addition, the fin tissue near the tail has grown back to normal levels.

In the video below, our neon tetra was cured (after around 1 week) from Neon Tetra Disease, after dosing Melafix.
Neon Tetra Disease Cause
As mentioned before, there is almost no information on neon tetra disease, even though it is a very common disease of neon tetras. Some say that it is caused by a Microsporidian parasite called Pleistophora hyphessobryconis.
There is also a closely related disease called “False Neon Tetra Disease”, which is caused by bacteria. The symptoms are so close that it is impossible to tell apart the two diseases without a microscope in a laboratory.
According to famous fish keeper Cory from Aquarium Co-op, Neon Tetra Disease is caused by Mycobacterium, which also causes fish tuberculosis.
Neon Tetra Disease Cure
Based on our experience, Melafix certainly seemed to cure the Neon Tetra Disease. Then again, theoretically Melafix works against bacterial diseases but not parasitical diseases. Hence, it may work for the cases of Neon Tetra Disease which are caused by bacteria, but not for those that are caused by parasites.
