Lesser Spiny Eel
Macrognathus aculeatus
Key differences: Generally smaller (up to 38 cm), has fewer dorsal spines (16-20), and typically exhibits a row of ocelli (eye-spots) along the dorsal fin base, rather than the 'tire-track' pattern of M. armatus. The snout is also less pronounced.
Half-banded Spiny Eel
Macrognathus pancalus
Key differences: Smaller (up to 18 cm), with a more slender body and a pattern of vertical or oblique bands on the upper half of the body, lacking the complex 'tire-track' pattern. Dorsal spines are fewer (16-20).
Fire Eel
Mastacembelus erythrotaenia
Key differences: Much larger (up to 1 meter), with a darker body coloration and prominent, bright red or orange stripes or blotches along its flanks. The pattern is distinctly different from the 'tire-track' of M. armatus.
