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. 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. O. acutirostra is reported to be more sensitive than the other two species in this genera and it is also the smallest and the prettiest. Can also be identified by the longer and narrower head and different pattern in the body. 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.
