The appearance of the Green Neon Tetra is something that throws many people off. This is the reason why these fish are misidentified so regularly.

From a distance or at first glance, they look a lot like the Cardinal tetras or basic Neon Tetra. Their body shape and primary blueish-green coloring are almost exactly the same!

The difference when it comes to color is when you begin to look at the red. While it is present, it’s a lot less visible (sometimes barely noticeable at all). To go along with it, the blueish-green area on their bodies is much more vibrant and generally brighter.

This combination makes the green coloration the most dominant and gives them their name.
