Could possibly be something more seriously wrong when fish lose scales. COuld be a parasite, fungus or some disease.
If you mean falling off then NO. But if you mean like the skin comes off, it happens occasionally and nothing is wrong.
The plural of scale is scales. As in "these scales must be wrong!"
A female goldfish grows at a slower rate then a male goldfish wrong!!!!!!!!!!!!!!! - A girl goldfish has a protruding anus, a male does not.
No. There is nothing wrong with a homosexual goldfish. Take good care of him.
It could just be the kind of goldfish. My fantail has a bulgy stomach but nothing's wrong with her.
It might be lonely if it is by itself.
That means that the goldfish is pregnant and the black dot will soon begin to grow!!
You can only kill a goldfish once. The sentence suggests it is possible to kill it more than once.
If your goldfish is left in the dark for a long time, it will eventually turn silver. Maybe this is the problem. It is harmless to the fish.
If you mean they are upside down, then they could be dead...
