Description

Geographic Origin and Biotope: Widespread across Africa (Nile, Niger, Lake Tanganyika). Prefers shallow, warm rivers and lakes with deep mud or sand bottoms.

Taxonomy and Morphology: Claroteidae monster. Reaches 70-90 cm. Unmistakable face: highly elongated snout ending in thick, fleshy, trunk-like lips surrounded by stiff barbels. Designed to plunge deep into the mud to root out food.

Social Behavior: The ultimate 'aquatic wild boar'. Extremely peaceful, not a hunter. Spends its life relentlessly bulldozing and overturning the substrate. Slow swimmer, but generates immense physical force.

Coloration and Sexual Dimorphism: Stunning as juveniles: cream base covered in large brown/purple irregular spots, perfectly matching a giraffe's coat. Sadly, adults fade into a drab, uniform muddy gray-brown. No dimorphism.

Care and observations

Tank Setup: Public aquarium sizing (1000-1500+ liters). NO AQUASCAPE WILL SURVIVE. It will uproot weighted plants and easily lift 20-pound rocks by shoving its snout underneath. Use only deep, fine sand and immovable, siliconed boulders. Heaters must be remote/sumped or it will smash them.

Feeding: Benthic omnivorous scavenger. Eats massive amounts of large pellets, earthworms, shrimp, and vegetables. Sifts sand constantly, expelling huge clouds of sand through its gills, which severely clogs filters.

Water Quality: Highly adaptable: pH 6.5-8.5 (often kept with Rift Lake cichlids). 23-28°C. Colossal waste producer requiring industrial pond filtration with heavy mechanical pre-filters for the expelled sand.

Compatibility: Peaceful, but destructive to decor. Great with large African Cichlids (Frontosa, large Haps) or mid-water giants. Will accidentally inhale tiny fish sleeping on the bottom. Avoid aggressive plecos that might suck its slime coat.

Reproduction: Unknown in aquaria; builds massive sandy crater nests in the wild.

Risks: Fatal stunting in standard tanks. Filter impeller destruction from chronic sand clouds. Chronic stress if kept bare-bottom (denies its natural rooting instinct).
