As mumma said, weekly water changes are necessary to maintain a healthy environment for your fish.... Every time I've had disease in my tank is when I have been lazy on water changed and usually any issues I have resolve when I get back to doing weekly water changes. Once your tank is cycled and you get a handle on your nitrate levels you will know how much water you will need to change weekly to keep nitrates less than 20ppm. Live plants can help, but weekly water changes still are necessary to replace essential nutrients and remove dissolved organic compounds amd.toxins that build up and can cause issues..
