I have been using ich-x for 9 days and white spots are not changing. I am doing daily water changes of 30%. I have a shubunkin goldfish with small dots on his tail, dorsal, and a few random ones on his body. The spots are very small - like grains of salt. In the same tank I have a black koi that is missing some scales and has a few small white spots on his face and an injury on his cheek and a white butterfly koi who has pink fins. Water parameters are great. Today I added some aquarium salt. My tank is 55 gallons. How do I help my fish get better so the entire tank doesn’t die?? This is a well established tank, have not added any new fish in 3 years. However, I have multiple tanks and do weekly water changes and had an outbreak from a couple Pictus cats bought at petsmart in another tank and I think I may have brought it to the other tanks from doing water changes and using the same gravel siphon. Please advise! I did lose another shubunkin from this tank a few weeks ago from dropsy. She did not have any of these symptoms. She looked like a pinecone. My pictures won’t upload from my phone or I would attach them for reference.
thanks for your help!!
