Fish are living creatures, and the value of oxygen in their life is as same as to humans. Fishes breathe by taking water through their mouth and passing it out through their gills. These creatures demand proper care and attention to thrive. Some fish survive in a large tank, and some can live in a bowl. The fish that live in a bowl can do so without oxygen or a pump. However, for that, choosing the right fish species is very important.
Fish species like Bettas or Siamese fighting fish are known to live in a bowl without oxygen or a pump. These fishes come to the water’s surface and breathe oxygen from the air. However, they can do so only when the water is clean and is changed frequently. If the water surface has dirt and dust, it can make breathing difficult for the fish.
It is important for enthusiasts to learn that despite how well a dish can survive in a bowl without a pump, it isn’t a long-term idea to go with. Bowls, with or without pumps, aren’t an ideal environment for fish to survive. They need space to swim around and a suitable environment to thrive, which bowls cannot provide for long. Also, like any other creatures, fishes need proper care and attention.
Therefore, before you decide to keep a fish in a bowl, make sure you are providing it with a careful and healthy environment.

Can fishes live without oxygen?
Logically No, Some fish species can live without air pumps, but no fish can survive without oxygen. Like any other living creature, fishes, too, need oxygen to survive. Fishes basically take oxygen from water using their gills and release CO2 in exchange.
There are some fish species that can tolerate low oxygen levels in the water, but each of them still needs oxygen to survive. Therefore to ensure the health and well-being of fish, it is important to maintain the oxygen level and water quality of the aquarium.

It is not recommended to keep any fish in a bowl without a proper filtration system and oxygen supply. Fish require clean and well-oxygenated water to survive and thrive, and a small bowl cannot provide these basic necessities.
Even small fish like bettas, which are often kept in bowls, need a filtered and oxygenated environment to live healthily. Without proper filtration and aeration, the water in a bowl can quickly become contaminated with harmful bacteria and toxins, leading to serious health problems for the fish.
If you are interested in keeping fish, it is important to provide them with a suitable environment that includes a filtration system and proper aeration. A small aquarium or fish tank with a capacity of at least five gallons can be a good option for some small fish species, such as guppies, tetras, and shrimp. Always research the specific needs of the fish species you want to keep and provide them with a suitable habitat to ensure their well-being.
While some fishes can survive in a bowl without oxygen or a pump, it isn’t an ideal environment for them. Fish require oxygen to survive, and if there isn’t proper aeration in the water bowl/ aquarium, it will soon become depleted of oxygen.
If you are looking to keep fish, make sure you provide them with the right environment to survive. Also, go without fish that can tolerate water with low oxygen levels and are beginners’ friendly.
