Black Widow Tetra (Gymnocorymbus ternetzi)

The Black Widow Tetra, also known as the Black Skirt Tetra, is a hardy and active schooling fish recognized by its distinct deep-bodied silhouette and striking black vertical bands. As they mature, the dark coloration softens into a sleek silvery-grey while maintaining their energetic group dynamics. They make robust, reliable community inhabitants that do well in planted setups with ample swimming space.
