My spotted sunfish have become infected with some sort of disease or infection. About a week or two ago I woke up and turn my tank lights on to find all my fish stressed. It seems my brown bullhead tried to eat one of my sunfish, whichever one he could catch. All my sunfish appear stressed even the fish that could not fit in his mouth. They would not eat and two days later my rock bass died due to what I assume was being stressed from almost getting eaten by my bullhead. Him and my redear are the smallest in the tank. Now after removing my bullhead they remain with an infection of some sort. Both my spotted sunfish have it the worst. My warmouth seem the least susceptible or the least affected. But both my green sunfish and my bluegill are getting cloudy eyes and off and on have the same disease as the spotteds. I don't what this is and hope someone can help my identify what it is and how I can treat it. So please let me know if you have any information that will help.
