Ruki Fish

Ruki were common fish Rahi with strong jaws. They would occasionally bite unsuspecting Matoran fingers that happen to stray into the water. They were also the natural enemies of Tarakava, and Ruki fish schools had been known to drive the larger Rahi off. They often pose a problem for Ga-Matoran, as they chew through nets, dams, etc. They have been seen in the waters off both Metru Nui and Mata Nui.
