Relevant Information: |
This genus is closely related to Hypoptopoma
but has a single line of enlarged odontoded running along the
body just above the lateral line and the posterior body and the
caudal peduncle are flat, whereas the genus Hypoptopoma
has a circular section. They also posses a narrower head than
the species of Hypoptopoma. Both genera have their eyes
high up on the head. The type species, Oxyropsis wrightiana
Eigenmann and Eigenmann (1889), occurs in the upper Amazon and
lower Ucayali River basins and is diagnosed among congeners by
the presence of seven ultimate median series trunk plates, which
are progressively smaller and narrower than the immediately preceding
plates, and by pectoral spine serrae either extremely reduced
in size (height less than one-sixth of the spine width) or absent.
There are at present (2010) three species in this genera namely
O. carinata
(Steindachner, 1879), O.
acutirostra Miranda Ribeiro, 1951
and O. wrightiana Eigenmann & Eigenmann, 1889 which
is the type species. Aquarium Care: Same care
as for Hypotopoma with long leaved plants or bamboo stalks
for them to rest on. Diet: Algae, vegetables,
tablet foods and
small live and frozen foods. Breeding: This species
has been bred (Evers, H.-G. & I.Seidel 2005) but the
fry were very difficult to raise. |
