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.
Penguin Tetras breed occasionally in an aquarium setting and a hospital or "breeding tank" will be necessary. During breeding time, the females will display a fuller looking belly, which help distinguish them from the males. Slightly acidic water is best for optimal breeding habits. After the eggs begin to hatch, 12 to 15 hours after being laid, removing the parents will reduce the number of lost fry.
