Dead Fish root tabs?

[TrueEnvy]

Hell everyone I have a fish tank not looking to good and I was wondering once it dies assuming it's going to do you guys think if I Barry it under my swords if it well act like a root tab? The fish is the size of a dime so I'm not fearful of the ammonia from the fish

I wouldn't for the same reason why you wouldn't want to put a dead fish directly under plants in a garden. With animal carcasses and certain manures they need time to break down and compost as they are too 'hot' to use right off.
