I had three orandas two of them died recently. I am wondering what they might of died from. All of the goldfish has white lumps on the top and on the sides of the humps of their heads. When the first fish died, I had found him the morning of and the top of hie hump on his head was gone( where the white lumps where). And this afternoon, after changing the tank, I found another one just floating. I didn't do anything different in the past two weeks. Does anyone know what this might of been?
