If your goldfish survive the first week in their tank, they will generally live 1-2 years. Keeping the water clean and not overfeeding will extend their lifespan.

If the goldfish is well cared for and no foreseen problems happen, it is known for goldfish to easily live anywhere from 10-20 years. Just make sure that if you want your goldfish to live this long, it needs to be in a non-crowded tank with a well balanced diet and plenty of clean water.
