This species was considered a synonym of Channa melasoma for a number of years prior to its revalidation by Ng. et al. (1996).

Specimens larger than around 120 mm SL can be distinguished by possession of a black spot in the centre of numerous body scales and a barred caudal-fin pattern, characters which are missing in both C. melasoma and the similar-looking C. cyanospilos.

This species is largely unsuitable for the home aquarium given its eventual size and natural behaviour, and we know of only a handful of private aquarists with the facilities required to house it long-term.

It’s currently illegal to import or own the species in the United States, United Kingdom and several other countries unless in possession of an official license.

No bubble nest is built and several thousand eggs simply float at the surface with both male and female remaining to defend the eggs and fry.

The eggs hatch after 24-36 hours depending on temperature and the fry are free swimming in a further 24 hours. At this point they resemble 6-7 mm long black tadpoles.

It is important to constantly feed…

This species is also traded as ‘golden cobra snakehead’ and is available in the aquarium trade on a regular basis.

It can be distinguished from other Channa species by the following combination of characters: 51-54 lateral line scales; 45-47 dorsal-fin rays; 28-30 anal-fin rays; 8-12 cheek scales; 50-52 total verte…

Endemic to southwestern Sri Lanka where it appears restricted to the so-called ‘wet zone’ (see ‘Habitat’).

Confirmed localities are all within the Bentota and Kelani river systems and Kottawa Forest Reserve in Galle district, Southern Province.

Type locality is given simply as ‘Habitat in India orientale’ and this appears to have caused confusion regarding the species’ distribution with it of…

Following Bonou and Teugels (1985), P. africana can be distinguished from congeners by the following combination of characters: colour pattern unique, comprising a series of 8-11 dark, chevron-shaped markings extending along the body posterior to the pectoral fins; 19-24 scales in the transverse series; lateral line complete with 73-83 pored scales; 45-48 dorsal-fin rays 45-48; 32-35 anal-fin rays.

Generally considered to have an enormous natural range extending from Iran to Taiwan and Bali, with records existing from Iran, Iraq, Afghanistan, Pakistan, Nepal, India, Sri Lanka, Bangladesh, Bhutan, China, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, Indonesia, and Singapore.

However there exists significant evidence to suggest that C. gachua as currently understood represents a complex of similar-looking species, and a taxonomic review of the group is clearly required.

C. micropeltes is also referred to as ‘Indonesian’, ‘red’, or ‘redline’ snakehead, the latter names in reference to the appearance of juveniles which often appear in the ornamental trade despite its unsuitability for home aquaria. It is somewhat hyperbolised in the media as a fearsome, invasive “monster” fish with a reputation for killing more fish than it can eat, and even the occasional human, although in reality…

C. bleheri is a popular aquarium fish though it remains unclear whether collection for the ornamentaol trade is having a detrimental effect on wild populations (see ‘Habitat’).

It’s one of several genus members to lack pelvic fins and can be further distinguished from other Channa species by the following combination of characters: sides of lower jaw with one large cycloid scale; lateral line complete with 46-50 scales; 14 pectoral-fin rays; 25 anal-fin rays; 4-11 irregular reddish orange markings on the caudal-fin
