Black Snakehead

This species can be told apart from the similar-looking congener C. baramensis (once considered synonymous with C. melasoma) by absence (vs. presence) of a black spot in the centre of numerous body scales and absence (vs. presence in specimens larger than 120 mm SL) of a barred caudal-fin pattern.

This species is often confused with the nominal congeners C. marulius (Hamilton, 1822) and C. melanoptera (Bleeker, 1855) with all three presenting taxonomic problems.
For example, C. marulioides exhibits a number of variations in colour pattern depending on collection locality with the most common possessing a brownish base colour with a series of dark, chevron-like markings along each flank and some scales margined posteriorly in white.

Forest Snakehead

Prefers a dimly-lit aquarium with plenty of cover in the form of live plants, driftwood branches, terracotta pipes, plant pots, etc., arranged to form a network of nooks, crannies, and shaded spots.
Surface vegetation such as Ceratopteris spp. is also appreciated and makes the fish less inclined to conceal themselves.

Based on its colour pattern and limited details regarding its natural habitat this species may be adapted to dwelling between and under rocks.
Alipurduar lies in the moist tropical region of floodplains and foothills of the eastern Himalayas commonly referred to as the Dooars or Duars, traditionally considered the gateway to Bhutan.

This unidentified species first appeared in the aquarium trade during 2009.
It’s easily told apart from similar-looking congeners by the patches of vivid red pigmentation surrounding the eye and sides of the mouth plus the thick, reddish, marginal band in the caudal-fin.
