1. Betta Fish 

Also known as Siamese fighting fish, bettas are one of the most popular fishes that can live in a bowl without an oxygen filter. Aside from being colorful and full of personality, they are tough little guys as well. 

They’re equipped with a special organ called the labyrinth, which allows them to breathe air from the surface. This means they can survive in water with low oxygen levels. Some betta fish owners also like keeping small aquatic plants in their bowls to provide some oxygen, as well as something for the fish to munch on.

2. Goldfish

The ever-popular goldfish is one of the best fishes for beginners and those with limited space. Although some types of goldfish need a lot of space and filtered water to survive, there are certain types, like the Comet Goldfish, which can live in a bowl without an oxygen filter. But remember, they do grow quite large, so you’ll need to upgrade their bowl as they grow.

3. Guppies

These small, colorful fish are very easy to care for and are perfect for beginners, as they don’t require much space or an oxygen filter to thrive. Guppies are also prolific breeders and can have baby fish, which is super exciting to watch!

4. Zebra Danios

This type of fish is known for its zebra-like stripes. Native to South Asian freshwater lakes, they are very energetic and love to swim around. These fish can survive in a wide range of water conditions, and they can easily thrive in fish bowls with aquatic plants supplying them with oxygen.

5. White Cloud Mountain Minnows

These fish are small, peaceful, and beautiful, making them one of the best fishes to keep in a bowl without oxygen filters. They can handle a wide range of temperatures and don’t need an oxygen filter to survive.

The Takeaway

It’s crucial to note that while these fishes can survive without an oxygen filter, they still require clean water to live a happy and healthy life. You should change a part of their water regularly to keep it clean and safe for them. Also, make sure their bowl is large enough for them to swim around comfortably. Never overcrowd your fish bowl!

Remember that every fish is unique and has its own needs. So, make sure to do your homework before bringing a new finned friend home. And who knows, maybe you’ll find that having a pet fish is just the right splash of fun and relaxation you’ve been looking for!
