Giraffe Catfish

Geographic Origin and Biotope: Vast range in the river basins of central and western Africa (Nile, Niger, Volta, Senegal, Lake Chad and Rift Lakes). Prefers sandy or muddy bottoms of shallow rivers and lakes.

Taxonomy and Morphology: Giraffe Catfish (Auchenoglanis occidentalis). A gigantic African siluriform. Possesses a very long and pointed snout for digging, fleshy lips and thick sensitive barbels. The stocky and massive body is protected by robust cranial bones.

Social Behavior: Of a very peaceful nature (often a "gentle giant"), but it is a clumsy and blind force of nature (it has tiny eyes). Incessantly sifts the bottom like a bulldozer, moving furnishings and frightening smaller fish.

Coloration and Sexual Dimorphism: Features a spectacular coloration, especially when young: a network of large dark spots on a yellow/cream background, which perfectly resembles the coat of a giraffe. Growing up, the spots tend to fade into olive-gray. No visible dimorphism.

Aquarium Setup: Mega-Aquarium fish (minimum 2 meters / 80 inches, but requires a tropical pond or 1000+ liters / 250+ gallons as an adult). Deep fine sand substrate mandatory for its excavator behavior. Rocks must be placed on the bottom glass, otherwise it will collapse them.

Diet and Feeding: Omnivore / Benthic detritivore. A real "vacuum cleaner". Will swallow massive sinking pellets, spirulina tablets, frozen shrimp, earthworms. Accidentally inhales small fish sleeping on the bottom at night.

Water Quality: Very robust. Tolerant to a wide pH range (from neutral to the alkaline of African lakes) and resists temporary oxygen drops. However, its huge mass requires titanic mechanical filtering systems to dispose of the enormous dirt raised.

Compatibility and Tankmates: Excellent companion for mega African cichlids (Frontosa, large Haps, West African Cichlids) or huge mid-water fish. Absolutely incompatible with live plants and fish under 15 cm (6 inches), which would be inhaled.

Aquarium Reproduction: Not documented in normal domestic aquariums given the enormous size and space requirements, although in nature they migrate to flooded plains to reproduce.

Risks and Diseases: Juveniles, very colorful ("cute"), are unscrupulously sold for 100-liter (25-gallon) tanks. Their lightning growth and brute force will smash unprotected glass heaters.
