O. flumucaudus was created when a population of O. brycomi wandered upriver into Zone 15. Since then, they've adapted to living in rivers. Their tail and side fins have become larger, making it easier to fight the current and prevent getting swept downstream. They've also lost the side fins on the sides of their tail to reduce drag. Additionally, they've made the relatively light change of having a lower internal salinity, so they don't get overhydrated by osmosis. This salinity change is due to a population of O. brycomi adapting to the lower salinity of Zone 15's delta.
Females lay around 5 - 8 eggs on plants in the beds of plants in the riverbottom, such as E. eodeasporous and E. folufusus. Simply due to the fact that there are no predators and plenty of food in Zone 15, it is rare that they do not reach maturity. Having adapted to a predator-less region, O. flumucaudus only reproduce when population numbers are low. This is an incredibly important adaptation, as if they continuously reproduced, it would result in overpopulation.
O. flumucaudus feed on river plants such as E. eodeasporous and E. folufusus. They adapted to a fully herbivorous lifestyle, which wasn't a huge change, as O. brycomi oten ate A. greenensis by accident while cleaning.
