Humans and many other animals have stomachs to digest their food, but goldfish have no stomach at all. They have different parts of their intestines that have to do the same job as a stomach, such as breaking down food and absorbing vitamins and minerals. Goldfish also have a unique way of digesting the food they eat.
Instead of using their stomach to break it down, they use their tongue. The tongue is a long, thin tube that extends from the bottom of the fish’s mouth to the top of its head. This process is called “digestive digestion,” and it’s the same process that occurs in humans when we eat food.

Do fishes have stomach?
The mouth, teeth and gill rakers are just some of the structural components of a fish’s digestive system. Some components are not present in all fish species. The mouth is the largest organ in the body and is responsible for swallowing, chewing, swallowing food and swallowing water. It is also the most important organ for digestion and absorption of nutrients.
The mouth also plays an important role in digestion of fats

Taste buds are located at the back of the tongue and are used to detect the taste of different foods.
How long does it take for a goldfish to digest food?
The fish will find enough food in the pond if they need it. They only need the algae that coats the pond liner. The cold temperatures slow the metabolism of your fish and food. The fish will take 3-4 days to digest their food.
If you have a pond with a lot of algae, you may want to add a small amount of salt to the water. If you do not add enough salt, your pond will become too acidic and your algae will grow out of control.
Do koi and goldfish have stomachs?
They don’t have stomachs, so they can’t eat a lot of food at once. This is one of the reasons that Koi spend a lot of time looking for food. They will eat anything that is small enough for them to eat.
Koi are also known to be very territorial and will defend their territory against other species of fish. If you are not careful, you could end up in a fight with one of these little guys.
How do goldfish eat without a stomach?
Goldfish don’t have a stomach in the sense that humans do. Goldfish digest food as it moves through their intestines and extract nutrients as the food passes through them. They don’t have teeth in their mouths, instead they use their gills to suck in air and then excrete it as waste.
In the wild goldfish eat a wide variety of prey;
- Crustaceans
- Insects
- Frogs
- Lizards
- Turtles
- Birds
- Rats
- Rabbits
- Small fish
- Small mammals such as mice
- Guinea pigs
- Hamsters
In captivity, they are fed a diet consisting of a mixture of live and frozen foods, as well as a small amount of dry food.
Does a goldfish have a heart?
The circulatory system of fish consists of a heart, blood and blood vessels. The heart is the largest muscle in the body and is responsible for pumping blood to all parts of the fish’s body.
In addition, the heart also pumps blood through the skin and into the gills, which are used to filter out toxins and other waste products. Fish also have a respiratory system that helps them breathe, and they use this system to regulate their body temperature.
How do fishes poop?
Well most of them will expel their feces through an anal vent (also called a cloaca), which is simply an opening for all wastes to leave the body. This also includes feces, urine, reproduction, and sometimes eggs or sperm. In the case of a female fish, she will use her anus to expel her eggs, which will then be deposited in the water column.
The eggs will hatch in a few days and the fish will continue to produce eggs until they are large enough to be released into the environment. Once released, the eggs can live for up to a year or more, depending on the species of fish and how long it takes for them to mature.
