Roi Grouper
Introduction: Roi (Cephalopholis argus) known by its Tahitian name and then its known as the peacock grouper. Its from the family Serranidae that is the ray-finned fish groupers and sea basses. The Etymology of the family of fish comes from a “Serranus” that can mean to be derived from saw. In the reefs of Hawaii there is not many predators to the “invasive” Roi as it allies itself with octopus and moray eels to share in the catching of prey, so it eats many of the native small fish with overpopulation. With the single species invading the reef there is an abundance of wild sources with fishermen doing their best to clear the waters of them. Subtropical coral reef areas are where they are found like the South-Pacific region. Roi are hermaphrodites that change between genders as there is three females to each male Roi.
