Black Skirt Tetra

Gymnocorymbus ternetzi

The Black Skirt Tetra (Gymnocorymbus ternetzi) is a popular freshwater fish known for its striking appearance and easygoing nature, making it a favorite among aquarists. Originating from the warm, slow-moving rivers and tributaries of South America, particularly in Paraguay and Brazil, this species is recognized for its distinctive black, ribbon-like dorsal and anal fins that drape elegantly like skirts, contrasting with their silvery-gray bodies.

The Black Skirt Tetra typically grows to about 3 inches in length and exhibits a peaceful temperament, making it an excellent choice for community tanks. It thrives in well-planted aquariums that mimic its natural habitat, where it can find refuge among the foliage while swimming in the open waters. These tetras are schooling fish, so they should be kept in groups of at least six to ensure their well-being and natural behavior. Hardy and adaptable, Black Skirt Tetras are suitable for both novice and experienced fish keepers, requiring minimal care while adding a touch of elegance and movement to any aquatic setup.
