The Tire-track Spiny Eel (Mastacembelus armatus / Theliya) is a nocturnal benthic predator in clean, gravel-bottom river channels. During daytime, it burrows into sand and coarse stones, leaving only its snout and eyes exposed. Between 2:00 AM and 5:00 AM, it leaves riverbank roots to hunt freshwater crabs and insect larvae in shallow gravel riffles (less than 40cm depth). Anglers wading quietly upstream use yellow LED lights to spot its patterned dorsal markings against quartz stones, taking fish with multi-pronged iron hand gigs (Vidhina Katuwa).

Wade upstream against the river current; stepping downstream washes cloudy silt ahead of your boots, blinding your view of bottom stones.

Commercial riverbed sand-mining destroys the gravel riffles and silt-free substrate needed by spiny eels and native river fish to spawn.

Spiny eels possess razor-sharp dorsal spines along their anterior back; handle live fish with thick canvas rags to avoid puncture wounds.

Artisanal spearing for household consumption is customary, but deploying chemical fish poisons or explosive charges in rivers carries strict penalties.
