The Penguin Tetra comes from the tributaries and rivers of South America and makes a wonderful addition to any community aquarium. They are pale to golden in color, and have a black vertical stripe that extends down the bottom half of the tail, giving an appearance similar to a penguin. The Penguin Tetra can be housed in an aquarium with other soft water fish. Tetras are a schooling fish that work well in groups of six or more fish of the same species. Live plants, rocks and driftwood help to enhance its natural habitat and provide hiding spaces.
