Channa micropeltes Breeding Guide
Overview
Channa micropeltes is among the largest snakeheads, capable of growing to 1.8 m (5.9 ft) and 30 kg (66 lb); even juveniles can reach up to 1.3 m. It is native to the fresh waters of Southeast Asia, occurring in the Mekong and Chao Phraya basins, the Malay Peninsula, Sumatra and Borneo, in lowland river and swamp habitats. It is a voracious predator that will chase and eat anything that fits in its mouth, but is rated harmless to humans on FishBase.
Spawning Behavior & Trigger
According to FishBase the species spawns in small streams with dense vegetation. Detailed parental-care, egg-count and nest-construction data are not given in the consulted sources and are therefore omitted.
Breeding Setup
- Natural spawning habitat: small streams with dense vegetation
- Environment: freshwater, benthopelagic, lowland river and swamp
- Temperature: 25-28 C
- Adult size up to 130 cm SL, weight up to about 20 kg
Invasive Note
The species is well-established and considered invasive in parts of Taiwan, such as Sun Moon Lake, and was recently detected in Sri Lanka's Deduru Oya reservoir (2024-2025), where it poses a significant threat to other fish species. In the United States it has been caught in several states but is not believed to be established. Live giant snakeheads must never be released into the wild.
