Introduction
Having an aquarium in your home or office can be a great way to add some color and life to your space. But, did you know that not all aquarium fishes need oxygen? Yes, you read that right! There are some species of fishes that can survive without the need for aeration or oxygen supply. In this article, we will discuss some of the most popular aquarium fishes that don't need oxygen.
Betta Fish
Betta fish, also known as Siamese fighting fish, are one of the most popular aquarium fishes that don't need oxygen. They have a unique labyrinth organ that allows them to breathe air from the surface. This means that they can survive in water with low oxygen levels. Betta fish are also known for their vibrant colors and long fins, making them a popular choice for many aquarium enthusiasts.
Gourami Fish
Gourami fish are another species that can survive in low-oxygen water. They have a labyrinth organ similar to that of Betta fish, which allows them to breathe air from the surface. Gourami fish are known for their peaceful demeanor and colorful appearance, making them a popular choice for many aquarium hobbyists.
Goldfish
Goldfish are one of the most common and well-known aquarium fishes. They can survive in low-oxygen water as they have a special ability to extract oxygen from the water's surface. Goldfish come in a variety of colors and sizes, making them a popular choice for many aquarium enthusiasts. However, it's important to note that goldfish require a larger tank to thrive than most other fishes.
Catfish
Catfish are popular aquarium fishes that can survive in low-oxygen water. They have a unique respiratory system that allows them to extract oxygen from the water's surface. Catfish come in a variety of sizes and colors, and they are known for their scavenging abilities, which can help keep the aquarium clean.
Conclusion
While many aquarium fishes require oxygen to survive, there are some species that can thrive in low-oxygen water. Betta fish, Gourami fish, Goldfish, and Catfish are just a few examples of fishes that don't need oxygen. These fishes can add some color and life to your aquarium without the need for additional equipment or maintenance. However, it's important to note that even though these fishes don't require oxygen, they still need proper care and attention to thrive.
