The Cardinal Tetra is one of the most iconic freshwater fish, known for its brilliant red and electric blue coloration that runs the full length of its body. When kept in groups, t hey create a stunning schooling display that instantly elevates the look of any aquarium. These fish thrive in groups of 6 or more, where their colors become more vibrant and their natural behavior stands out. Their smooth, synchronized movement brings a clean and professional look to planted and community tanks. Cardinal Tetras are peaceful and do best with other calm, non-aggressive species such as rasboras, corydoras, and small gouramis.
