White Skirt Tetra, also known as White Widow Tetra or Petticoat Tetra, is a peaceful and hardy freshwater fish, popular for beginner aquarists. It's a color variation of the Black Skirt Tetra, originating from South America. White Skirt Tetras are characterized by their elongated body, flowing anal fin (the "skirt"), and mostly pearly white coloration. They are omnivores, thriving in planted tanks with subdued lighting and enjoy being kept in schools of five or more.
