Green neon or Faux neon, real jewelry for nano aquarium

Paracheirodon simulans is the smallest species of neon tetra. The maximum length is about 2.5cm.

This species should not be confused with the neon costello, Hemigrammus hyanuary, which is also sometimes called "neon green". This is the reason why some people call Paracheirodon simulans the “blue neon”.

Despite this confusion, Paracheirodon simulans cannot be confused with any other species. It is only in this neon tetra that the intense bright neon stripe extends from the tip of the snout to the tip of the caudal peduncle.
