Top 10 Cold-Water Fish That Never Die 1. Goldfish

When it comes to fish that can survive without oxygen, the first thing that comes to my mind is goldfish. I don't need to introduce goldfish in detail. As one of the three most popular ornamental fish in the world, it is well known that goldfish are really very easy to keep. Not only do you not have to worry about the water temperature, you don't even have to worry too much about oxygen.

2. Red snapper

The appearance of the horse-sleeve fish is small, exquisite and cute. The most distinctive feature is that they have two long thin "whiskers" under their heads. They have a black line from their eyes to their tails, and their bodies are covered with white spots, like pearls, which is probably why they are also called pearl fish. There is no need to add oxygen to the water when raising horse-sleeve fish.

3. Manlong fish

Similar to the pearly cormorants above, mandrakes are also ornamental fish of the family Mylodonidae, so like cormorants, they can live in water with relatively low oxygen levels. Mandrakes are gentle in nature, have low requirements for water quality, and can float to the surface to breathe oxygen in the air, so there is no need to add oxygen to the water when raising mandrakes.

4. Chinese fighting fish

Chinese fighting fish is also an easy fish to breed. As mentioned in the previous article, Chinese fighting fish can tolerate temperatures as low as 10 degrees Celsius. And like the previous three fish, the oxygen saturation in their blood is higher than normal. So they can live well in water without an oxygen pump.

6. Red Skirt Fish

The red skirt fish is also called the lantern fish. Like the black skirt fish, they are small tropical fish with a body length of about 3 cm. Because the back half of the body resembles a red skirt, it is named red skirt fish. The red skirt fish is also a fish that is relatively resistant to low oxygen, and the color of the fish tail changes with the change of water temperature, which is also quite beautiful.

7. Chinese fighting fish

Compared with Thai fighting fish, Chinese fighting fish may not be as colorful, but their wonderful patterns also fascinate fish lovers. As a native fish, Chinese fighting fish is more adaptable to the domestic climate environment, and people don’t need to worry too much about heating equipment. The habits of Chinese fighting fish and Thai fighting fish are similar. It is best to raise Chinese fighting fish alone. There is no need to use an oxygen pump to add oxygen. Just change the water regularly to keep the water environment clean and oxygenated.

8. Red zebrafish

The red zebrafish is a small and hardy ornamental fish. It has bright colors and neat zebra stripes. It is worth keeping as an ornamental fish. However, the red zebrafish has a bad temper. It is very aggressive in snatching food and often bullies other fish. The strong red zebrafish can be regarded as the "tank tyrant" in the aquarium. The hardy red zebrafish does not consume much oxygen on a daily basis, and can live comfortably even without an oxygen pump.

9. View the back of the blue

The Greenback is a small ornamental fish that is very friendly to new friends. They are hardy and do not require a high breeding environment. They are small and can live in a small water environment. As long as the water change is done well, they can live well even without filtration, oxygen pumps and other devices. As a cold water fish, they have very low requirements for water temperature and can survive in water temperatures of 0~40℃, and can adapt to the domestic climate environment.

10. Blue Manlong

Blue Mandrakes are also popular ornamental fish in the market. They are hardy and do not require high oxygen content in the water. They do not consume much oxygen on a daily basis. They can maintain a regular water change frequency, which generally does not cause any harm to their daily life. However, they are a bit mean and are not suitable for mixed breeding with ornamental fish with beautiful fins. Blue Mandrakes are likely to nibble their fins.
