Neon tetras are some of the most popular freshwater aquarium fish in the world. Their vibrant blue and red stripes, peaceful behavior, and small size make them a favorite for beginners and experienced aquarists alike.
These fish are schooling species, which means they look best in groups, swimming together like a shimmering rainbow.
Designing a neon tetra fish tank is more than just choosing decorations it’s about creating a healthy, beautiful, and engaging environment where the fish can thrive and shine.
Whether you want a planted jungle-style aquarium, a minimalist modern tank, or a community tank filled with multiple species, there are endless ways to showcase their beauty.
