I have a fancy Koi about 2 years old who started to become bloated. I looked through pictures on-line and it appeared to have developed dropsy. I am not sure what caused it as the other fish are fine. I quarantined the fish and gave it a salt bath. It has started to reduce the swelling after about 3 weeks. The wierd thing is the last two days I have found long orange almost worm like waste (from the fish I am assuming) floating. Has anybody ever heard of such a thing? Either this fish is making an improbable recovery or is about to die.
