The goldfish, Carassius auratus, is a fish that lives in freshwater. It belongs to the family Cyprinidae and the order Cypriniformes. It is one of the most popular aquarium fish and is often kept as a pet in indoor aquariums. Goldfish that were let out into the wild is now a problem in some parts of North America.

The goldfish is a small fish that comes from East Asia. It is in the same family as the Prussian carp and the crucian carp. It was first bred for color in imperial China more than a thousand years ago, and since then, several different breeds have been made. Goldfish breeds are very different in size, shape, fin arrangement, and color.

Types

Goldfish come in a lot of different kinds. People usually divide them into standard (with a long body) and fancy (with a round body) types. The most popular pet fish is the common Comet Goldfish. Even though they are usually sold in pet stores when they are very small, these fish can grow to be 14-16 inches long and may need up to 100 gallons of water.

Shubunkin and Sarasa goldfish have the same body shape, but Shubunkin and Sarasa goldfish often have more colors, like red, white, black, and yellow. There are many different kinds of fancy goldfish, and their bodies have changed in many ways to fit them. The Oranda, Ranchu, Telescope, Fantail, Celestial, and Moor are some of these breeds. They look like eggs or have round bodies.

Because of how their bodies are made, they don’t usually get as big as long-body goldfish, and they may have some structural problems. Because their eyes stick out and their fins are so thin, these fish are more likely to have problems with buoyancy, spinal disease, and injuries from accidents. The Oranda goldfish has a fleshy growth on its head called a “wen,” which may need to be cut off if it gets too big and covers the eyes or face.

Size: How Big Do Goldfishes Get?

Remember that goldfish living inside small aquariums tend to be about 1 to 2 inches (2.5 to 5.1 cm) long. Goldfish may get bigger if they are moved to bigger fish tanks, but they usually don’t get any longer than 6 inches (15 cm). So, goldfish can grow to about 14 inches (36 cm) in ponds and in the wild.

Reproduction

Goldfish can only get big enough to breed if they have enough water and the right food. Most goldfish breed in ponds or other places where they are kept as pets. Most animals breed after a big change in temperature, usually in the spring. Male gold fish chase after pregnant females (females with eggs) and bump and nudge them to get them to drop their eggs.

Goldfish lay eggs, just like all other cyprinids. Their eggs are sticky and stick to water plants, usually thick ones like Cabomba, Elodea, or a spawning mop. In 48 to 72 hours, the eggs will hatch.

Within a week or so, the fry starts to take its final shape, but it may take up to a year for them to turn the golden color of an adult goldfish. Until then, they look like their wild ancestors and are metallic brown. The fry grows quickly in the first few weeks of life. This is because they are likely to be eaten by adult goldfish or other fish and insects in their environment.

How Long Do Goldfish Live

Goldfish usually live between 10 and 15 years, but some types can live up to 30 years if they are cared for well. Many goldfish don’t live as long as they can because they don’t have the right place to live. Both their behavioral and physical needs must be met by their housing.

Can Dogs Eat Goldfish

Even if your dog begs, you shouldn’t give him Goldfish crackers because they aren’t a very healthy snack. Some of the things they are made of could be dangerous in large amounts. Your dog could get sick from the salt, onion powder, and garlic powder.
