What is it?

Flexibacter is commonly called mouth fungus, but it is not a fungus at all but a bacterial infection.

How did it get there?

Flexibacter is caused by poor water quality.

Treatment

Any antibacterial medication that treats against both gram-positive and gram-negative bacterial infections will work. Water should be changed before beginning treatments.

Prevention

• Make sure to keep your water cleaned regularly. Smaller tanks without filters will need more water changed more frequently than a larger tank with a filter.
