Goldfish are neither mammals nor reptiles; they are fish. Specifically, they belong to the family Cyprinidae and are a freshwater species of the carp family. Unlike mammals, goldfish do not have fur or mammary glands, and unlike reptiles, they do not have scales or lay eggs in the same manner. They are cold-blooded and breathe underwater using gills.
