Etymology

Channa: from the Latin channe, used to refer to an unspecified species of sea perch. marulioides: from the specific name marulius and Ancient Greek εἶδος (eido…

Distribution

Native to southern Thailand (below the Isthmus of Kra), Malaysia, and Indonesia, including the Greater Sunda Islands. Type locality is 'Sambas, western Borneo,…

Habitat

Tends to inhabit larger river channels and inland lakes such as the Danau Sentarum system in Kalimantan, Borneo.

Aquarium size

Suitable only for public installations or the very largest private aquaria.

Maintenance

Relatively unfussy although some surface cover in the form of floating or overhanging vegetation or branches is appreciated. Unlike most Channa spp. it's pelag…

An obligate predator which probably feeds on smaller fishes, amphibians and terrestrial insects in nature but in most cases adapts well to dead alternatives in captivity.

Some specimens even accept dried foods though these should never form the staple diet.

Young fish can be offered chironomid larvae (bloodworm), small earthworms, chopped prawn and suchlike while adults will accept strips of fish flesh, whole prawns/shrimp, mussels, etc.

This species should not be fed mammalian or avian meat such as beef heart or chicken since some of the lipids contained in these cannot be properly metabolised by the fish and may cause excess fat deposits and even organ degeneration.

Similarly there is no benefit in the use of 'feeder' fish such as livebearers or small goldfish which carry with them the risk of parasite or disease introduction and at any rate tend not have a high nutritional value unless properly conditioned beforehand.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Behaviour and compatibility

Best-maintained in a species-specific aquarium. Juveniles and subadults are relatively peaceful with one another but become aggressive when they reach sexual m…

Notes

This species is often confused with the nominal congeners C. marulius (Hamilton, 1822) and C. melanoptera (Bleeker, 1855) with all three presenting taxonomic p…
