One of my six discus has not kept up with the others in growth. The fish has also begun having white stringy feces, which I know is a sign of intestinal parasites.
Should the tank be treated or just the fish having the problem? They have been together in a 55G bare tank for about 4 months.
Any suggestions for treatment would be greatly appreciated. I did treat the same fish with Melafix and Pimafix about 2 months ago because it was not eating and had frayed fins.
Thanks.
