Hey, I have 5 neons in a 28 gal. tank. I have had the fish for 3 weeks now after cycling the tank for 1 week. I have been doing regular water changes and filter cleanings. They all eat well and swim with no problem.
Now the problem, while feeding them tonight I noticed 1 of them has a orange/white spot right at the base of is back where it meets the fin. Not sure if it is neon tetra diseases and whoud hate to jump too conclusions as the tank was a gift to my son who loves them.
Any help would be appreciated.
Thanks in advance.

Erratic swimming, weight loss, loss of color are symptoms of neon tetra disease.
