[4] Parachanna obscura is a medium-sized carnivorous fish with an elongated shape tapered on both ends, and is covered in medium circular scales (cycloid).

[4] The coloration of P. obscura adults and juveniles consists of dark blackish, rounded spots found along the flanks.

A baby fish initially has an ochre base coloration with a black stripe down its flank from the snout to the caudal fin.

[3] The obscure snakehead is both benthopelagic (bottom dweller) and potamodromous (freshwater migratory), and thrives in harsh environments, including muddy waters.

[3][4] This fish lives in streams, ponds, rivers, lakes, marshes, lagoons, swamps, and floodplains.

[3][4] The obscure snakehead is also known as the "sleeping fish", as it spends much of its time motionless among the aquatic vegetation.

Incubation time varies depending on the temperature of the water and amount of light to which the eggs are exposed.
