How big are feeder goldfish?

Feeder goldfish are typically small, growing to only 1-2 inches in length. These small goldfish are also known as feeder fish, baitfish, or live food fish, and are often sold as live food for larger or predatory fish. It's important to note that feeder goldfish are generally kept in poor conditions and may carry diseases or parasites, making them unsuitable for release into natural waters or mixing with other fish populations.
