No, Melafix is not effective against columnaris Pimafix may be helpful. Did I mention Indian Almond Leaves (IAL)? They are also known as catappa leaves. They are said to have antibacterial and antifungal properties.

Ok, well since it looks bacterial, frist thing is to separate. Columnaris is transmitted by healthy fish eating a dead infected body. Never good to have an infected fish die in an ST. So after isolation next step would to lower the temp to 70-ish, should slow down the growth of it and the CPD may act better at cooler temps.

Then diligent WC everyday for the best chance of the fish fighting it off.
