The climbing perch (Anabas testudineus) is one of the most fascinating freshwater fish in Asia. Known for its ability to survive in harsh conditions and even “walk” on land, this fish has amazed locals, scientists, and anglers for centuries. In Cambodia and other Southeast Asian countries, it is also an important food source and cultural symbol.
In this article, we’ll explore some of the most amazing facts about the climbing perch and why it’s called a true survivor of the waters.
1. Native to Southeast Asia
The climbing perch is widely found in Cambodia, Vietnam, Thailand, Laos, India, Bangladesh, and Malaysia. You’ll often spot it in rice fields, swamps, ponds, and canals. Because of its resilience, it can live in waters where many other fish cannot survive.
2. Can Breathe Air Like a Snakehead
Unlike ordinary fish, the climbing perch has a special labyrinth organ that allows it to breathe air. This means it can survive in low-oxygen water and even live out of water for 6–10 hours as long as it stays moist.
3. The Famous “Walking Fish”
Climbing perch are nicknamed walking fish because they can travel across land by flipping their fins and body. This behavior helps them move between ponds or rice fields, especially during the wet season. While some people claim they “climb trees,” they actually just wriggle up muddy banks, roots, or grasses.
4. A Popular Food Fish
In Cambodia and neighboring countries, climbing perch is a common market fish. Its meat is firm, tasty, and often used in soups, grilled dishes, or fried recipes. Many farmers also raise climbing perch in ponds because they are easy to care for and very hardy.
5. Survival Champion

This fish can survive in harsh conditions where many other species die. It tolerates muddy water, low oxygen, and even periods without water. Its ability to adapt makes it one of the toughest freshwater species in the world.
6. Cultural Importance
For many Southeast Asian communities, climbing perch is more than food—it’s part of daily life. Its resilience symbolizes strength and survival, and in some traditions, it is even believed to bring good luck.
