If you are running with a septic tank, flushing a DEAD fish will not effect the environment. Septics tanks are often started / seeded with a dead fox or other such animal to get the bacteria to a level that will process the waste. Does this sound familiar?? similar to a fish tank maybe??. If you are not on septic tanks I am not sure, obviously water treatment is going to help the water and many sanitary items are flushed and removed, whereas on land fill the body would just decay over time.
