Ruby Tetra (Axelrodia riesei)

Small, vibrant, and eye-catching Ruby Tetras are one of the best nano fish for planted aquariums and peaceful community tanks.

With their rich red coloration, these tiny schooling fish create a striking visual effect when kept in groups. Ruby Tetras are perfect for aquascaping setups and smaller aquariums, adding bold color without overwhelming the tank.

They thrive in planted environments and are especially stunning against green plants and natural decor.
