Had A Couple Neons Die

[bailey0789]

In the past week ive found two of my neons floating in the tank covered in a milky white substance. Almost looks like wet cotton. At first I thought it was killed by tankmates Glo Lights or Red minor tetras. Im now wondering if this is a disease. Any info would be helpful and thanks in advance. Its a ten gallon tank. 2 Red Minors and 3 Glo Lights with about 3 neons. Now down to one neon.

It sounds like they have cotton wool disease. You can treat it with salt baths. Once the fish are treated add 4 red minors, 3 glolights, and 5 neons. Tetras should in in schools of 6+.
