The dwarf snakehead (scientific name: Channa gachua) is a type of fish. It belongs to the Channidae family. You might hear the name "dwarf snakehead" used for other small snakehead fish too.
This fish lives in fresh water across southern Asia. You can find it from Iran all the way to Indonesia. Scientists think C. gachua is actually a group of very similar fish species. They are so alike that they are often called a "species complex". This means there might be three or four different species hiding under one name! Researchers are still studying them to tell them apart. Some fish, like Channa harcourtbutleri, have already been identified as separate species. Also, the C. gachua living in eastern areas is often called C. limbata. The fish found only in Sri Lanka is sometimes known as C. kelaartii.

Different Types of Dwarf Snakeheads
Scientists have found that dwarf snakeheads from western and eastern areas are genetically different. This means their DNA is not the same. Because of this, some scientists think the western fish are C. gachua and the eastern ones are C. limbata. The fish in Sri Lanka are also very different genetically. So, some people call them C. kelaartii. Even though these groups are genetically distinct, they look very similar!
Why Are Dwarf Snakeheads Important?
