Fish Fanatic
2 of my neons have lost the red on thier bellies, not the blue just the red. There is 5 of them and they shoal with 3 cardinals and a celestial danio. Other members of the tank include khuli's, pencilfish, 6 danios, otocynclis, a female betta. The water tests are all fine. Tank has been going a year so is fully mature. No problems with tank mates. The rest of my neons aren't doing this, (yet) help
