The goldfish tank size myth suggests that goldfish can live in small tanks, but the truth is that they need a lot of space to thrive. Goldfish produce a lot of waste and need room to swim and grow properly. It is recommended to provide at least 20 gallons of water per goldfish to ensure their health and well-being.
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.

Actually, goldfish do have a stomach, but it's very small, probably about the size of one of their eyes.
No, goldfish will not grow to the size of their tank. They will continue to grow and may become stunted or unhealthy if kept in a tank that is too small for their size.
A goldfish can grow up to 12 inches in length, depending on factors like genetics, diet, water quality, and tank size. These factors can influence the growth size of a goldfish.
The size of a tank can affect the growth of goldfish. A larger tank provides more space for the goldfish to swim and grow, allowing them to reach their full potential size. In a smaller tank, goldfish may be stunted in growth due to limited space and water quality issues.
The only issue I've heard about concerning housing goldfish together is any big difference in body shape or size. Bigger goldfish might be more aggressive towards smaller goldfish. Also, the more streamlined breeds (koi, comet, etc.) might have an easier time snatching up food, leaving little behind for the pudgier, slower fish (fantail, ryukin, etc.).
The size of a goldfishes brain would depend upon the size of the goldfish. It is however quite large enough to enable the goldfish to survive. By comparison to mammals though it is small.
The size of a goldfish tank can affect the growth of the goldfish. A larger tank provides more space for the goldfish to swim and grow, leading to healthier and potentially larger fish. In contrast, a smaller tank can restrict the fish's movement and growth, potentially stunting their development.
no because, a baby goldfish takes 1 year to grow.
Yes, goldfish can grow according to their environment. Factors such as tank size, water quality, and diet can influence the growth of a goldfish.
