Cave Fish were small fish-like Rahi.
Many schools of Cave Fish made their home in the Silver Sea surrounding Metru Nui and also in Ga-Metru. During the Great Cataclysm, the schools of Cave Fish migrated to the waters of Aqua Magna around Mata Nui and integrating into the natural ecosystem.
Abilities and Traits
When the Cave Fish feel threatened; they will defend themselves by absorbing large amounts of Liquid Protodermis though their skin and inflating themselves to make them appear larger in an effort to scare off their predators.
In Ga-Metru, Ga-Matoran used the decreased Cave Fish to absorb leaks in their Protodermis purification vats.
