Paracheirodon simulans "Green Neon Tetra" is imported in from Colombia, Venezuela, and Brazil out the Rio Orinoco and Rio Negro. These wild fish add plenty of color to the aquarium exhibiting a brilliant blue stripe down the side of the body, much like its popular cousin, Paracheirodon axelrodi "Cardinal Tetra". Green Neons that come from different tributaries seem to show slight color variations. I've noticed that the specimens collected out of Colombia seem to display a touch of red on their side. While the fish only reach a maximum size of about an inch, this striking blue bar can be seen all the way across the room. Now I'm sure you're a little worried about all the reports you've read about the fish coming from blackwater biotopes with a pH no greater than that of battery acid. Luckily, we have conditioned all of our fish to handle a neutral pH so that you don't have to worry about breaking out the RO unit. Unless you are endeavoring to breed Green Neons, I do not feel keeping them in such acidic conditions is as important as, keeping them in clean water.
