Posted by Max Gandara on on 14th Sep 2025
The Congo Tetra is a striking freshwater fish known for its iridescent body, flowing fins, and peaceful nature. Native to the Congo River Basin in Africa, this tetra displays shades of blue, violet, and gold that shimmer under aquarium lighting, making it a beautiful centerpiece for larger community tanks.
Congo Tetras are schooling fish that thrive best in groups of six or more. When kept together, they show off their full colors and graceful swimming patterns. They prefer spacious aquariums with plenty of open swimming areas, plants, and dim lighting to mimic their natural habitat.
These tetras are omnivores and enjoy a varied diet of high-quality flakes, pellets, and occasional frozen or live foods. A balanced diet helps maintain their vibrant coloration and overall health.
