Matoro's Rahi was a business run by the Matoran Matoro on the island city of Metru Nui. Spending much of his time studying Rahi in the Archives, he would sometimes find small animals that the Onu-Matoran did not want. Being a good friend of them, the Onu-Matoran would give the Rahi to Matoro to keep. He would then sell them in Ko-Metru as pets for other Matoran. Naturally, this business ended when Matoro was taken to Mata Nui after the Great Cataclysm.
