Neon Tetra Disease is a KILLER! My Neon Tetra colony has been wiped out because of this disease. This horrible disease will take the lives of your fish one by one. When you see that you have an infected fish, make sure you separate it because once another fish starts eating the dead fish, the disease is contracted. There is no known cure for this disease so it is best to euthanise the infected fish or to keep them alone. Link to my Instagram page: https://www.instagram.com/cwaquahobby...
