Cleaning a Goldfish tank is an essential routine to maintain optimal living conditions. It’s ideal to conduct partial water changes — about 20 to 30% of the water — weekly. This keeps nitrate levels within permissible limits and ensures a healthy environment for your Goldfish.
A more thorough cleaning should be performed monthly or more frequently if needed, including vacuuming the substrate and wiping off algae from the tank’s sides. Regular maintenance helps prevent diseases, maintains water quality, and ultimately ensures the health and longevity of your fish.
