Nice tank, a good start! When you find a plan fauna. Recommend , Hemigrammus Rhodostomus - Rummy Nose Tetra, Paracheirodon Axelrod - Cardinal Tetra, Hypesobrycon herbertaxelrodi. You decides!
Thanks some good ideas! Already have rummynose in another tank and love them, but dont want the same fish in multiple tanks. Cardinals are also always a good go to, and I've always wanted black neons too.
