How long can a goldfish travel?

The shortest distance a goldfish can travel before it dies is around three meters (12 feet) . With a little more experience, your goldfish will be able to reach distances that are up to five meters. However, even then, this distance can vary greatly depending on the fish's physical environment, its personal preferences and how you care for it.

This makes it ideal for indoor aquaria or a special pet shop aquarium, where the fish are kept at the proper temperature and kept in a cool, dark tank rather than a warm, lit tank. In the home, they can also be kept indoors with air conditioner air filters that run continuously, rather than just periodically.

How do goldfish get their bright colors?
Goldfish don't have an eyes in their heads, so they rely on their eyes to tell the difference between bright and darker parts of their environment. Goldfish that are kept in a bright habitat can even get darker stripes on their fins, with yellow and pink stripes that are easy for them to tell apart, says Lea, because their eyes are relatively flat.

The other color variation is the way they respond to various stimuli, such as light flashing in the water or a noise, or a strong scent of something on something else. Goldfish also use a chemical called dinocaprolene to regulate their body temperature, and if their food is kept at the same temperature, the fish will stay calm enough to look at the food itself without being bothered by it.

How do goldfish swim?
Goldfish don't have a swim bladder, but they do use its internal structure to propel themselves forward in an upright, round swimming motion. This movement gives them a unique swimming style that is unique to them and provides them with a lot of advantages: They can reach a great height in the water, unlike other fish, allowing them to get into deeper, deeper pools as well as a number of depths in a single move.

What happens when your goldfish accidentally swims into your aquarium?
Just as with a normal goldfish, goldfish are vulnerable to many things: being picked up by a predator, being accidentally struck, even being bitten by a fish.

That's because these fish are unable to swim very far when they are young, when they need to travel a lot before they are able to swim very easily, and when they start swimming as adults, they have to slow down for air.

"If you put a goldfish in an aquarium where you can see it all the time, they don't know they need any air to get where they need to go, " says Lea.
