Monopelte Whiptail Catfish

Sturisoma monopelte is native to upper Orinoco tributaries in Venezuela and is of particular interest to ichthyologists and serious hobbyists for its distinctive morphological feature — a region of the body with notably reduced plate coverage compared to other Sturisoma species. This characteristic influenced its specific epithet and sets it apart in the genus.

In the aquarium, this species requires the same general care as other Sturisoma — clean, well-oxygenated water, driftwood and smooth hard surfaces for grazing, and a varied plant-based diet. Its rarity in the hobby means that husbandry data is limited, but experienced keepers of other Sturisoma species should find it manageable.

Imports of Sturisoma monopelte are infrequent and typically come as bycatch in broader Orinoco fish exports from Venezuela. Hobbyists who obtain this species should consider participating in captive breeding efforts to establish a sustainable population in the hobby.
