Taxonomy & naming
Channallabes teugelsi was described in 2007 by Renata Devaere, Dominique Adriaens and Walter Verraes, part of a wave of taxonomic work on Central African clariid catfishes in the early 2000s. It belongs to the family Clariidae, the airbreathing or walking catfishes, and to the genus Channallabes, a small group of eel-shaped African clariids first erected by Günther in 1873.
The genus Channallabes currently holds about six recognised species, all restricted to Central African river systems. Older literature on African clariids sometimes lumped anguilliform genera like Channallabes together with other elongated walking-catfish lineages under broader or different generic names before the group was revised; the Catalog of Fishes treats Channallabes teugelsi as the valid combination, and that is the name used here. The species epithet honours a researcher associated with the ichthyology of the region (the pattern is typical of clariid species named for colleagues or collectors), though the cache consulted for this profile does not confirm the specific dedication.
Morphology
Channallabes teugelsi has the hallmark body plan of its genus: strongly elongated and anguilliform, or eel-like, rather than the deeper-bodied shape of a typical catfish. The head is small and somewhat flattened, the dorsal and anal fins run long and low along most of the body, and the body itself lacks scales, like all clariids. A distinguishing feature noted for this species is a whitish spot on the roof of the skull, and its pectoral spines carry fine serrations along their edge — a detail used to separate it from its close relatives within Channallabes.
Maximum size has not been confirmed by the sources available for this profile; treat any figure as unverified until a primary source is checked. As in all Clariidae, the pectoral and (where present) dorsal spines can lock rigid and are edged with serrations capable of snagging a net or jabbing a careless hand, and the naked, scaleless skin makes this species — like other airbreathing catfishes — more sensitive to copper and many medications than scaled fish.
Habitat
Channallabes teugelsi is known from the Congo River drainage in Central Africa, with records associated with Gabon and the Republic of Congo. Like other members of its genus it is presumed to favour the flooded-forest and swampy backwater habitats where anguilliform clariids are typically found — shallow, vegetation-choked pools and leaf litter where a slender, air-breathing body is an advantage for pushing through tight spaces and surviving in oxygen-poor water.
Specific water chemistry data — temperature range, pH and hardness — was not available in the sources consulted for this profile. Central African Congo-basin blackwater and swamp habitats are often soft and acidic, but that should be treated as a general regional expectation rather than a confirmed figure for this particular species until better data is found.
Feeding
No species-specific dietary study was found for Channallabes teugelsi in the sources consulted. Based on the general biology of Clariidae and its close relatives, it is reasonable to expect a nocturnal benthic omnivore or micro-predator that forages along the bottom and through leaf litter after dark for small invertebrates and detritus, but this should be treated as an inference from family-level biology rather than a confirmed fact for this species.
In an aquarium setting, clariid catfishes of this build generally accept sinking pellets, frozen foods (bloodworm, brine shrimp) and other prepared foods once settled, offered after lights-out so a shy, nocturnal fish is not out-competed by more active tankmates.
Mating
No description of courtship or spawning behaviour for Channallabes teugelsi was found in the sources consulted for this profile. Data is sparse to the point that even the general reproductive strategy of the genus is not well documented in accessible literature.
Breeding
There is no confirmed record of Channallabes teugelsi being bred in the aquarium, and no wild breeding-behaviour data was available in the sources consulted. Given how little is documented even for basic biology, it would be inaccurate to assign this species a specific breeding mode — do not assume open-water egg-scattering or any other strategy without a source. As with many recently described, poorly studied clariids, it should be treated as effectively unbred in captivity until better information surfaces.
In the aquarium
Channallabes teugelsi is essentially unknown in the hobby, and firm aquarium-care figures — tank size, adult length, exact water parameters — could not be confirmed from the sources available for this profile. Prospective keepers should treat any care guidance as provisional and lean on the general precautions that apply to airbreathing clariid catfishes: the skin is scaleless, so dose copper-based and many other medications conservatively; the spines are stiff and can lock, and may carry fine serrations capable of snagging a net or scratching a hand, so move the fish in a container rather than netting it; and as an air-breather it will need regular access to the surface and should not be kept in a tightly sealed tank.
Because the adult size of this species has not been confirmed here, do not assume it stays small — many anguilliform Clariidae grow to a substantial length despite their slender build, and undersizing a tank for an elongated, actively burrowing catfish is a common care mistake. Secure lids are advisable for any clariid, since many are accomplished escape artists capable of wriggling overland.
Conservation
Channallabes teugelsi has not been formally assessed by the IUCN Red List and its status is Not Evaluated. As a narrow-range Congo-basin endemic described only in 2007, it likely faces the general pressures affecting Central African freshwater habitats — deforestation, water-quality changes and habitat disturbance in the Gabon/Republic of Congo portion of the Congo drainage — but no species-specific conservation assessment or population data was found in the sources consulted for this profile.
