i have a 36g bow front tank for 10 years. I had 2 upsidedown asian catfish 2 angelfish. A freind gave me 3 more angelfish and a gouramie. All of the angelfish seemed to come down with a case of finrot i treated with api fin & body. Alomg with 25% water changes. It seemed to be under control then fins started rotting again. All water levels are within range. ( i use api master test kit). Although ph is normal i know the angels like it low. 2 of the angels have died 2 are on their way out and the last is showing signs of rot. I started with melafix. Will do water change tomorrow. Is there anything else i can do and why is it not effecting the other breeds of fish in the tank?
