I have a question that hopefully someone can answer. My Friend has an Oranda (panda). For the last few months he started to swim sideways. At closer examining him we noticed at first that his dorsal fin was not functioning right. Then we noticed some discoloration around the body and the Dorsal. It is turning pink in color and now looks like it is caving in along the spine.? We now noticed in the last month that the pigment around the other fins is doing the same. He now swims ok, but when he stops he is side ways.. Eats great attitude it great. Checked the water. All is great. Other Orandas in the tank are not affected by this at all. Can't really seem to find any information on this issue. He may have a swim bladder issue, but I think it has to do more with the Dorsal fin not functioning properly. I will try to get some pics this weekend if anyone needs to see it. Any help or suggestions would be great appreciated.. Thank you.
