Aquarium Fish That Doesn't Need Oxygen
Aquariums are a beautiful addition to any home or office. They provide a relaxing and peaceful environment, and the fish within them are fascinating to watch. However, one common misconception about aquariums is that all fish need oxygen. While most fish do require oxygen to survive, there are a few species that don't. In this article, we will explore some of the aquarium fish that don't need oxygen.
1. Betta Fish
Betta fish, also known as Siamese fighting fish, are one of the most popular aquarium fish. They are known for their beautiful colors and long flowing fins. Betta fish are able to breathe air from the surface of the water using a special organ called a labyrinth organ. This allows them to survive in water with low oxygen levels.
2. Paradise Fish
Paradise fish are another species that can survive in water with low oxygen levels. They are known for their bright colors and aggressive behavior. Like Betta fish, Paradise fish have a labyrinth organ that allows them to breathe air from the surface of the water.
3. Gourami Fish
Gourami fish are a popular choice for aquarium owners due to their peaceful nature and unique appearance. They are able to breathe air from the surface of the water using a special organ called a labyrinth organ. This allows them to survive in water with low oxygen levels.
4. Zebra Danio Fish
Zebra Danio fish, also known as zebrafish, are a small and active species that are easy to care for. They are able to survive in water with low oxygen levels due to their efficient gills and ability to extract oxygen from the water.
5. Kuhli Loach Fish
Kuhli Loach fish are a peaceful and social species that are often kept in groups. They are able to survive in water with low oxygen levels due to their ability to extract oxygen from the water through their skin.
Conclusion
While most aquarium fish require oxygen to survive, there are a few species that don't. Betta fish, Paradise fish, Gourami fish, Zebra Danio fish, and Kuhli Loach fish are all able to survive in water with low oxygen levels. If you are interested in keeping a low-oxygen aquarium, be sure to research the specific needs of the fish you plan to keep and provide them with a suitable environment.
