The Black Neon Tetra is another great fish for planted aquariums where slightly acidic water conditions are present. The Black Neon Tetra has a yellow-green stripe that runs the length of the body with a black region under the yellow-green stripe. It looks really neat when you see a school of this fish darting about.

This tetra is even smaller than the Cardinal Tetra and Neon Tetra and will display the same schooling behavior when kept in small groups of 6 or more. They are very peaceful and should not be kept with larger fish capable of eating them.
