Uaru is a small genus of cichlis with only two species. Uaru may come from the Amazon word for toad. This may because of their slightly frog like shape, or their coloration. It is also possible that it comes from the words uara aru, "resembling a (hand) mirror" possibly from the Genus's pancake shaped members. These are also known as Triangle Chichlids, possibly refering to the triangular shape of adults. There are two known types of uaru, and there is possibly a third kind.; The Orange-fleck Uaru is sometimes imported and sold in Europe. However, this is not really a Uaru.
