Relevant Information:

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 nattereri and Scleromystax 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: Similar 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.
