EtymologyChannallabes: From the Greek, channe, meaning anchovy and allabes, the name of a Nilotic fish (a kind of lamprey); in reference to the shape of the fish. From the Greek prefix a- meaning without and pous, meaning foot; in reference to the lack of pelvic fins.

Size 600mm or 23.6" SL. Find near, nearer or same sized spp.
IdentificationDistinguished by the extremely elongate body, reduced cranial shield, confluent median fins, small eyes and absence of pelvic fins.
SexingThe genital papilla, which is to the right of the anus as you look at the fish with its head to the left, is elongated and pointed in males while it is round and relatively larger (and larger than the anus) in females. In ventral view especially, females are much broader in the body than males of equal age and rearing practices. It may be hard to see with the naked eye.
General RemarksRecent research has documented this species' ability to feed terrestially (videos above). The catfish's neck is especially flexible, with specialized vertebrae that allow it to hold its head up out of the water without using fins. The fish's diet provided the scientists with the first clue to its remarkable behaviour - it mainly eats beetles which are found on land. The researchers speculate that a similar feeding strategy could have been used by the first vertebrates to emerge from the oceans.

The fish is known to burrow into the substrate and has been caught by hook and line in waterlogged areas adjacent to rivers and swamps simply by digging a hole and fishing in the resulting pool.

FeedingWill take all manner of pelleted food, as well as frozen/live food (the latter being preferred).
FurnitureProvide plenty of driftwood for the fish to hide. Ensure that the tank cover is tight-fitting/weighed down, they are capable of climbing out.
CompatibilityA peaceful fish that is best suited for the West African biotope tank. Ideal tankmates include mid-sized African barbs, tetras, and cichlids.
BreedingNot reported.
