How big is a goldfish stomach?

Goldfish have a relatively small stomach compared to their body size. Their stomach is about the size of their eyeball. However, goldfish are known to be voracious eaters and can consume a large amount of food in a short period of time. They do not have a stomach valve, which means that food can pass through their digestive system very quickly. Goldfish typically eat a diet of flakes, pellets, or live food, such as brine shrimp or daphnia. It is important to feed goldfish the correct amount of food to avoid overfeeding, which can lead to health problems.
