Assamese Snakehead

Assamese Snakehead (Channa stewartii)

The Assamese Snakehead (Channa stewartii) is a stunning freshwater fish native to the rivers and streams of Assam and other regions of Northeast India. Known for its striking body pattern, vivid coloration, and bold personality, this species is a favorite among aquarists who admire exotic and predatory fish. Unlike larger snakehead species, the Assamese Snakehead grows to a more manageable size, usually around 10–12 inches, making it suitable for aquarists with medium-to-large tanks.

This snakehead thrives in aquariums of at least 55–75 gallons, with ample swimming space and secure hiding areas. An ideal setup includes a sandy or fine gravel substrate, plenty of driftwood, rock caves, and floating plants to help diffuse lighting. Like many snakeheads, the Assamese Snakehead has a labyrinth-like organ that allows it to breathe atmospheric air, so a tightly fitted tank cover is essential to prevent escapes.

Water parameters for Channa stewartii should mimic its natural environment. It prefers temperatures between 72–82°F (22–28°C), a pH range of 6.0–7.5, and slightly soft to moderately hard water. These conditions not only promote health but also bring out the fish’s stunning coloration, with shades of blue, gold, and green shimmering under aquarium lights.

The Assamese Snakehead is carnivorous and requires a protein-rich diet. In captivity, they thrive on live and frozen foods such as worms, shrimp, small fish, crickets, and high-quality carnivore pellets. Their hunting instincts and intelligence make them captivating to observe during feeding times. However, they are territorial and aggressive, especially towards other fish of similar size, so it’s generally recommended to keep them alone or in carefully monitored pairs.

With proper care, Channa stewartii can live for 8–12 years in captivity, making it a long-term commitment for experienced fishkeepers. Its exotic beauty, interactive nature, and resilience make it a rewarding species for those prepared to meet its needs.
