Which fish easily tolerate a lack of oxygen?

In Australia, a fish has been found that can live on land for a week. It belongs to the perch family. A strange fish can live both in water and on land, as it has a gill and the likeness of lungs. There is also the Anabas fish, which can travel overland and even climb trees, all because near the gills, the fish have teeth, with the help of which, it can crawl pretty quickly. But the championship is occupied by Mangrove Rivulus, which can live without air, which is in water, for two months. This fish needs about a day to turn its gills and start breathing through the skin.
