I was hoping some of my fellow fish lovers could help me out. I rescued 3 goldfish back in October. When I got them home, Lucifer had red streaks on his fins. I figured it had come from him thrashing about a bit on the way home in the small travel tank (maybe broke some blood vessels).
Well, here we are in Dec and some of the streaks are still there. Now he also has a white spot on his eye. So I was thinking maybe it was some type of fungal or bacterial infection going on. He is still very active, eating, and no clamped fins or lethargy. All of the other fish are healthy and active. I've been treating the water with a combo of Pimafix and Melafix, for over a week, but the white spot and red fins are still there. I did the recommended 25% water change after a week of treatment. The water is still pretty hazy from the meds. My water parameters are good. No ammonia or nitrites, new water is always treated with Prime, and nitrates are always at 40 ppm or below, which is in the safe zone according to my test strips. I use a marine land canister filter that has 4 filter cartridges and 2 bio wheels. I can't take out the charcoal like is recommend for the meds because the cartridges are sealed shut. But I figured some of the meds must still be staying in the water and not getting filtered out with the water looking so hazy.
Do any of my fish friends on here have any suggestions of what to do/treat for next? Any and all advice would be much appreciated!
I attached a pic of the white spot on Lucifer's eye.
