carassius auratus auratus

Question: How long do goldfish live?

Answer: Like the maximum size, the lifespan of goldfish is also variable. The record is 43 years, but it is uncommon for goldfish to live this long. Goldfish usually live quite long when kept in large aquarium or outdoor ponds, up to 15 to 20 years is not unheard of. In smaller or heated aquarium, a lifespan of five to ten years is quite achievable. As mentioned, the most important factors when keeping goldfish in small aquarium are careful feeding and adequate filtration and/or maintenance.
