Ammonia and Nitrites will begin to rise and this will ultimately lead to the death of your Zebra Danios. A filter helps to keep the water quality high and also oxygenates the water which is essential for the health of your fish. Another benefit of having a filter is that it provides a place for beneficial bacteria to live. These bacteria help to break down ammonia and nitrites in the water which further helps to improve water quality. So while Zebra Danios can technically live without a filter, it is not something that is generally recommended.
