So I have had 7 neons in my 20gal for about 2 weeks now. One of the smaller ones has lost some of his/her color on their right side, below and just forward of their dorsal fin. Instead of having his blue stripe run down his body there is a break in it that is grey/white. It also seems like his stripes are not as reflective as the others. Does anyone know if this is normal or the beginning of a fishy illness? I test my water every three days or so and it continues to look fine. The most recent readings are as follows:
pH 6.8-7.0
Ammonia 0ppm
Nitrite 0ppm
Nitrate 5.0-10.0 ppm
My temp is set at 78 F

Sounds like it could be Neon Tetra Disease.

Hi mcdonald,
If you could post a pic, it might help others identify the problem.
I thought one of my neons had NTD also, but it turned out to be a fungus.
Either way, you should quarantine him, both are contagious. Is he showing any other symptoms?

Good luck, I hope he gets to be feeling better.
