I've had a solid blue male Betta in a 5 gal planted tank for about 10 months now. Today I noticed that his face is turning white. It's definately not ich. Last week I noticed he was getting a marking that looked like a mustache over his mouth that was either dark blue or black. Now he's turning white in the area. Is something wrong? Or do Betta's turn colors?
