||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.
punctata, O. fimbriata plus
one new species in O. asterophysa. 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
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.
