Paracheirodon simulans

The green neon tetra is the smallest of the three Paracheirodon tetras and one of the most underappreciated. It has a longer, more vivid blue-green stripe with a shorter red patch compared to the cardinal tetra. It is a strict blackwater species requiring soft, very acidic water and is best kept in biotope setups with tannin-stained water and low light.
