Tuberculosis in Bettas?

Tuberculosis is an infection of the lungs. So it actually makes sense that betta fish can become infected. This is because they have an organ called the "labyrinth" that acts as a lung and allows them to breathe surface air. Treatment for this disease is very tough, but you need to take immediate action. Tuberculosis is communicable which means you could catch it from your betta.
