Goldfish scales fell off

[ducas005]

Hi all.. One of my gold fish (pond comet) was housed in a bigger aquarium where i noticed other fish (comets, shubukin) picking (nipping) on her. Today I moved her to a small 10 g tank all by herself. I noticed her tail was reduced in size (clamped) and scales near that has fallen off.

Does anyone know how to cure this gold fish? It was with me for a very long time and I hope it can be cured. It still moves fast and eats vigorously.. but I never noticed it fight other fish, always running away when bullied.

He prolly lost the scale due to nipping or bumping into something, not mcu hto worry about as long as not to many are gone.
As for the clamped fins, is there any ammonia in the tank, my comets clamped up tight when I had ammonia in the tank.

goldfish died

No i moved it to the smaller tank which had no ammonia and it was the only fish there. But it died this morning -( ) I guess it was old age too.
