My poor little fish(red-capped oranda) is sick bigtime....what should I do....he is swollen and puffed around his face....he is so puffy and losing all of his scales....and now he is swimming upside down....what should I do for him???? I am so worried...Please.....any advice would be muchly appreciated....I him so much.....and if there is anything I can do for him.....his water is normal and all other fish like him are thriving wonderfully.....except him....

I think you should post this in the emergency section of the forum, but until then:

Tank size? Filtration? Any new fish/plants?

He doesn't sound good. Does he look like a pinecone with his scales sticking out?

I hope that you can give us more info on the tank conditions and how long has this been going on with your goldy?
