I got a new fish tank that's 29 gallons. I waited three days to add the fish and now it smells horrible and is a little cloudy. I added the fish Monday. What happened?
you tank is cycling. you probably took advise from some fish store guy about how to prepare your tank for fish. that was your first mistake. your tank will continue to go through the nitrogen cycle for the next several weeks. if it's possible return the fish to the store and cycle your tank properly before adding fish. to learn more about the nitrogen cycle google it.
Also, you should have only added one fish originally. If you add a lot of fish at once you'll get the ammonia spike Put one fish in, wait up to a week before adding any more.
