Etymology:

Auchenoglanis: Greek, auchen = neck + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish.

General Notes:

Giraffe catfish are very big fish as the video clip demonstrates and they grow remarkably quickly, you have been warned!!! Apart from their size giraffe catfish are easy to keep, they are tolerant of a wide range of conditions and will readily accept all food offered. They are entirely peaceful and will mix with a range of other species. They don't eat plants but due to their size and feeding habits plants are almost certain to be up-rooted, artificial plants are recommended over real plants with this species.

Feeding

Giraffe catfish will accept live and frozen food along with suitably sized pellets, they are bold feeders and may even learn to be hand fed with a little patience.

Sexing

There are no external differences between the sexes with giraffe catfish and so there is no reliable way to sex them.

Breeding

Giraffe catfish have never been bred in captivity. In the wild they are nest builders and the male alone defends the brood.

Wild status

The giraffe catfish is listed as Least Concern as it has a wide distribution, with no known major widespread threats. In N Africa it is listed as vulnerable. For the majority of its range, no major threats to this species are known. In eastern Africa, it is threatened by loss of habitat, as well as overfishing. In north Africa, dams, water pollution (agriculture, domestic and commercial/industrial), groundwater extraction and drought all pose possible threats to this species
