||There is at present (2010)
nine species in this genera and they used to all be in the Pimelodidae
genus. Their body is long and slender with a depressed head. The
head is covered dorsally with a layer of thick skin. The occipital
process is short and does not meet the predorsal plate, and the
fontanel is narrow and usually extends to the occipital base,
with or without an interruption behind the eyes. The dorsal and
pectoral fins lack spines. The skin of these fish is usually naked
(scaleless) and they exhibit three pairs of barbels. In its natural
habitat there is a report of H. armillatus seeming to
prefer sand and a gravel bottom with a relatively fast flow of
water or sluggish waters of the same stream where aquatic vegetation
was lacking. Aquarium Care: Not usually kept
in aquaria but there is a report that H. leptos was kept
on a soft substrate with subdued lighting as they are quite secretive.
Diet: Most prepared foods but prefers live.
South America: La
Plata and Uruguay River basins and coastal drainages of southern
Brazil. Type locality: Rio de la Plata.
