I have one of my 4 rainbows with what seems like shedding. It is on both sides going vertically. One line only, not whole body. All other fish are good, I hope. He is not scratching. He could have been picked on, but both sides?no fish that big. Water quality is good: 0 ammonia, 0 nitrites. ph 7.2 water changed tuesday, very stable, established tank 7+years. Have had the fish atleast 3 years.
Do they shed? He is still eating, swimming, doing all the same fishy things.
