Hi! I have treated my fish with 3 antibiotics as they showed signs of sickness( fatigue, fungus, swimming rarely, fins clamped down)
I have 2 blackmoors and 1 goldfish. Since the antibiotics I have seen slight improvement in the blackmoor but the goldfish is getting worse. I have done 50% water change every week and put new filter in. I also got the water tested and the readings were as follows:
Now the nitrite is bad level so I am putting in nitrivec everyday for 14 days.
Today I have noticed my goldfish has blister like things on each side gil. And now one side is red like it's bleeding. I will try attach a photo.
Please can someone tell me what to do nxt???
I am so sad and dnt know what to do. Would appreciate good advice xx
