Green Neon Tetra Fish Guide
The Green Neon Tetra (Paracheirodon simulans) is a tiny, bright fish with a shiny green/blue stripe along its body and a soft red glow on the belly. People love them because they look magical in groups and are fun to watch as they swim together. They are smaller and a bit rarer than the common neon tetra, so many hobbyists enjoy adding a school of Green Neons to a planted tank.
