Spawning injuries.

[Beno]

One of my goldfish is looking very bashed up from spawning. Her scales look injured, some have gone black, now she is covered in a mould looking fungus??? I have started treating the water for fungus. Is this the right thing to do???
I inherited the pond last November when I moved home. It’s all new to me.

Spawning can me aggressive at times as I recently lost a female due to it. Issue it the males won't stop so best to isolate and treat away from the pond.
Add some pics so we can confirm the injuries and how to treat.

I think I might take her away from the rest of the fish for now as you don't need to treat the whole group and it will give her some peace and quiet to hopefully recover. Use some of the pond water to keep her in and run a little aeration in her holding tub or tank while you treat her.
