Can anyone offer me some advice on this goldfish? The photograph shows a small area of missing scales behind the gill on one side. The fish doesn't show any sign of distress, but the problem has been present for a couple of weeks now and does not appear to be improving.
The fish is one of two kept in a 100-litre tank. A 30-litre water change is done each week and the most recent water parameters were all healthy. The fish has been in the tank for three months and is eating well (as ever!).
I am relatively new to fish-keeping and don't know whether this is something I could or should treat.
