Can be differentiated from
the genus Parotocinclus by the absence of
an adipose fin. Rarely imported and is rare in nature
due to pollution of its habitats. This species is
found alongside Corydoras
prionotos and has the same colouration
as these two Callichthyidae species. Colouration:
It has a base grey colour with a black band with traces
of a gold sheen (hence common name) along the flanks
and has a small hooked shaped growth on the bony plate
behind the head. Diet: Mainly nocturnal
and feeds on algae. Aquarium Care:
Feeds on plants and roots; in groups of 5 or more
individuals; minimum aquarium size 60 cm. (24ins).
Due to the catchment area in Rio de Janeiro this Otocinclus
needs to be kept in cooler waters. Remarks:
looking to the São Paulo version further south
which is said to be another species, which was placed
into a new genera, Macrotocinclus, but it
is now back to the original Otocinclus genus.
South America:Brazil, vicinity of Rio de Janeiro. Type
