CONGO TETRA

Congo Tetra – Vibrant and Hardy Freshwater Fish

Congo Tetras (Phenacogrammus interruptus) are a beautiful addition to any aquarium. This freshwater fish, which is native to the Congo River Basin in Central Africa, is well-known throughout the world for its graceful, flowing fins and iridescent rainbow scales. Congo Tetras are among the most common schooling fish in home aquariums because they are calm, resilient, and simple to maintain, regardless of your level of experience.

Your tank will be more balanced and active if you keep both Congo Tetra males and females together. They flourish in groups due to their gregarious, schooling nature, and their dynamic, synchronized swimming makes any community aquarium come to life.
