Cave Fish are small fish-like Rahi.
The Cave Fish species was created by the Makuta using Viruses and Liquid Protodermis as a Rahi to inhabit the Matoran Universe.
Many Cave Fish made their home in the Silver Sea surrounding Metru Nui. In Ga-Metru, Ga-Matoran used deceased Cave Fish to absorb leaks in Protodermis purification vats.
After the Great Cataclysm, a number of Cave Fish migrated to the waters of Aqua Magna around the island of Mata Nui, and were integrated into the local ecosystem. After the Matoran returned to Metru Nui, some Cave Fish followed, but others remained on Aqua Magna in the waters of what was once known as Ga-Wahi.
After the Great Spirit Robot was critically damaged in the Battle of Bara Magna, many Cave Fish were transferred to Spherus Magna.
Abilities and Traits
When threatened, Cave Fish defend themselves by absorbing large amounts of Liquid Protodermis, inflating themselves in an effort to appear larger and scare off predators.
