I have some danio's for over 6 months, and today when changing the water I noticed that two of them had blood red skin along one side starting at the mouth area.
Can anyone help me as I am unsure as to what this is or how to treat it if possible.
The tank is a Jewel 120 litre and around 10 - 15% of the water is changed every week.
