I have a koi that has bloated up. From past experience I first thought it was pregnant but now I'm sure it's Bloat, Pinecone Syndrome or dropsy. None of my other fish are affected A picture of the fish is here- http://glorybug.blogspot.com/2009/06/fish-one.html I am a natural pond enthusist, and not an expert. I have cleaned the filter and put tea tree oil and alfalfa in the pond. Would adding more salt help? Is there anything else I can do that is natural? This fish has lived longer than the info I've researched- even though bloated, it's been almost 3 months and she's still alive. As I've said, I'm no expert- my children think the fish is male. Any help on fish bloat that is natural? I never take the koi out of the pond, so isolation won't work. I've heard that sometimes koi with bloat get better for no reason at all. Are there ways to encourage this? Thanks for any help you can offer.
