One of my mum's 24 year old koi seems to have dropsy. It has the pinecone effect, but has been like this for about a month and is still eating. She has isolated it in one pond, but has not yet treated. Our local koi center said that it probably wouldnt survive anyway!!! I disagree. The pond is 52" wide x 86" long x 15" deep. The koi probably weighs about 10 lb, it is about 18" long!! Is salt the best treatment? If so, how much? Any advice would be gratefully received.
