I have a few neons in a 10 gallon tank. One neon has been showing strange symptoms. His coloring is darker, and his spine is curving to one way, giving him a "bent" appearence. I looked online and saw it might be fish tuberculosis. Then I wondered why it hit my neons, but no other fish. What do you think?
