It's important to note that Goldie's size was an anomaly and not representative of the average goldfish size. The size of a goldfish depends on several factors, including genetics, environment, and diet.
What is the largest goldfish?
The largest goldfish ever recorded was a pet goldfish named "Goldie". Goldie was a common goldfish that lived in a pond in England. He was measured at 47 inches (119 cm) long and weighed approximately 44 pounds (20 kg). This is much larger than the average goldfish, which typically grows to be around 6-8 inches (15-20 cm) long.
