Widow Tetra (Gymnocorymbus ternetzi) is a popular freshwater aquarium fish known for its striking black and colorful patterns. These small, peaceful fish are active swimmers that add liveliness and visual interest to any community tank. Available in multiple color varieties including standard black widow, albino, and other selectively bred colors, they are versatile and attractive additions to aquariums of all sizes.
Widow Tetras are schooling fish, so they thrive best in groups of 6 or more. They prefer well-planted tanks with open swimming areas and moderate water flow. Hardy and easy to care for, Widow Tetras are suitable for both beginners and experienced aquarists. They are omnivorous, feeding on flakes, pellets, and small live or frozen foods.
