Hey guys so I have a small group of bullhead cats about one inch long. they are wild caught. recently they began dyeing and noticed small white cloudy spots on them and fins look frayed also. skin is slightly getting discolored paleish in places. breathing is heavy. So far i added an air stone, 50% water change, and installed a heater at 85. I did this just a few min ago. I am positive its not ich any ideas? Salt? I never used meds on any fish so I am a bit nervous to do so.
Thanks guys!!!
