Well actually ii noticed a couple of days ago that mt fish is actually skin peeling on his nose and ii want to know why because it is really worrying me in case sum at happens to him, basically hes a fancy goldfish and he lives in a bowl? Anyone have any suggestions?
Put a LITTLE salt in the water!
The water is too acidic.
This happened to my gold fish too once when I didn't change the water (5 gallon / 21 litre tank) along with some of the scales turning black. I've changed the water now so let's see what happens!
