The Golden Black Widow also is known as the White Widow Tetra is a man-made hybrid of the Black Widow Tetra which is a schooling fish that comes Rio Paraguay, Rio Guapore and Bolivia in South America. They are best kept in groups of six or more to create a healthy, happy school of fish. Avoid housing them in the same tank as smaller fish (particularly those with long, flowing fins) as Black Widows do occasionally nip.
Black Widow Tetras originate from the small, slower tributaries and creeks of the Guapore and Paraguay Rivers in Brazil, where the forest canopy provides both shade and food. They congregate near the surface of the water where they eat insects, crustaceans and small worms.
White Widow Tetras remain relatively small, reaching an adult length of approximately 5cm. Hybrids, such as the long-finned varieties, tend to be a bit larger.
A schooling fish by nature, the White Widow Tetras are best kept in groups of at least six or more. They make an excellent community fish due to their peaceful nature however they sometimes known to nip the fins of slower-moving fish, particularly those with long, flowing fins such as Siamese Fighters or Angelfish.
They readily accept virtually any food, including live, fresh, frozen, freeze-dried, or flake foods. For the breed’s optimal health, provide a variety of foods, which can include high-quality flake foods, brine shrimp, and any type of worms, as well as vegetable supplements such as spirulina.
