Was known until recently (2011)
as Doras eigenmanni until a new paper by
Birindelli, JLO and MH Sabaj Pérez (2011) asigned
a new genera, Ossancora to this species.
Ossancora was proposed to include three previously
named species O.
fimbriataplus one new species in
The four species are distinguished from each other
by the branching on the maxillary and mandibular barbels,
the morphologies of the swimbladder and bony plates
in front of the dorsal fin, and the number of teeth
on the upper and lower jaws. Can sometimes be seen,
and sold as Opsodoras
stuebelii, which has a longer snout
and lacks the body and caudal spots and also grows
larger. It has been misidentified, especially in the
mid 1980s in the hobby when catfish were just beginning
to get a fan base in the U. K. Similar to Ossancora
punctata (previously Doras punctatus)
which has bands in the caudal fin against spots in
O.eigenmanni. Aquarium Care:
Very peaceful addition to a community aquarium. This
is another doradid that prefers safety in numbers
assuming that you can purchase them. Recommended that
you keep at least 4 specimens together. Good water
quality is required. Diet: Finely
shredded shrimp and bloodworm.
Upper Paraguay River drainage.
