Mastacembelus armatus, commonly known as the tire track eel or zig-zag eel, is native to South and Southeast Asia. Its geographical distribution includes countries such as India, Pakistan, Nepal, Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam, and Malaysia.

Mastacembelus armatus typically inhabits freshwater environments. These include rivers, streams, ponds, and lakes with slow-moving or still waters. The species is often found in areas with muddy or sandy substrates and abundant aquatic vegetation. The climate in its native regions varies from tropical to subtropical, with a monsoon season bringing heavy rains that affect water levels and flow.

As a bottom-dwelling species, Mastacembelus armatus plays a role in the ecosystem as both a predator and prey. It feeds on small invertebrates, crustaceans, and occasionally small fish, contributing to the control of these populations. The species is adapted to low-light conditions and often hides among submerged vegetation or within the substrate during the day, becoming more active at night.
