In a few publications the genus Olyra has been placed in its own family Olyridae: sub family Olyrinae. The family was erected by Hora in 1936. Mo(1991) revised the Bagridae family and proposed a new classification for Olyra. He classed on a cladistic pattern focusing on osteological characters. On the basis of his cladogram of the Bagridae family it was found the Olyra is deeply nested within other bagrid genera and as such cannot be retained as a separate family. Aquarium Care: Will fit into a community tank alongside other Asian fish such as the larger species of Danios and Barbs. It is extremely territorial with its own kind so would need to be given plenty of hiding places to curb this aggresion. Diet: Most aquarium based foods such as frozen (bloodworms) live and tablet foods. Etymology: The genus name Olyra: etymology not explained, perhaps from Olyra, Greek for a kind of grain (perhaps rye), or Olyra Linneaus 1759, a genus of neotropical grasses, perhaps referring to similarity of some Olyra leaves (pointed at one end) to pointed tail of O. longicaudata. The specific name longicaudata: longus, long; caudata, tailed, probably referring to the middle rays of the tail “prolonged to a lengthened point”. Remarks: Olyra kempi Chaudhuri, 1912 is now a synomyn of O. longicaudata.
