i currently have 3 neon tetra's floating happly around my 20 gal tank. I checked my water parameters and everythin is in balance. I noticed that one of my neon tetra's likes to lose all of its color. It kinda gets dark. Then just as quick as that happens, it goes back to its normal vibriant self. Does happen in a blink of an eye, but over several hours. Any ideas? disease?! Or is he just special?
