The Black Otocinclus is known from the Rio S?o Jo?o
drainage and other small coastal tributaries running to the Ba?a de Guanabara
and to the Ba?a de Sepetiba in Rio de Janeiro State. This is a charming
miniature Loricariid that is ideally suited to a quiet, heavily planted
aquarium. It is a peaceful fish that is best kept in good sized groups (6+) in
a mature aquarium with plenty of shady hiding spots amongst plants, driftwood,
and slate caves. Tankmates should be of similar size and temperament e.g. some
of the smaller tetra and Corydoras species, or dwarf cichlids (Apistogramma,
Mikrogeophagus etc). Avoid tankmates that are boisterous at feeding times, as
these shy little catfish will not compete well. This species can be rather
delicate when first imported - always ensure new arrivals are well rested, and
quarantine any new purchases to ensure they settle in well before adding to the
main aquarium.




Omnivorous. Offer a varied diet consisting of sinking
catfish pellets, algae wafers, and frozen foods such as bloodworm, daphnia,
cyclops etc. Provide vegetable matter such as slices of cucumber or courgette
on a regular basis.




A handful of aquarists claim to have bred this egg laying
species, but details are few and far between. The fish apparently clean the
spawning site/s together (often the underside of leaves or the aquarium glass)
and spawn in a T position similar to that of Corydoras. The fry are tiny and
feeding presents quite a challenge.
