The green neon tetra (Paracheirodon simulans) is a freshwater fish of the characin family (family Characidae) of order Characiformes. It is native to the upper Orinoco and Negro Rivers in South America.
This fish is similar in appearance to the closely related and better-known neon tetra, but it is slightly smaller and its red patch is less pronounced, while the blue-green areas of the upper body are more brilliant. Also, its body is slimmer than that of the neon tetra. It grows to a maximum overall length of about 2.5 cm (1 in).
Like the other Paracheirodon species, the green neon tetra is kept as an aquarium fish, but it is less commonly seen than either the true neon tetra or the cardinal tetra.
P. simulans is also sometimes called the blue or false neon. Hyphessobrycon simulans and Cheirodon simulans are obsolete synonyms.
This fish loses its brilliant blue and red colors when lights are switched off in the dark, but regains it when lights are switched on again.

Famous quotes containing the words green and/or neon:
“The gentle serpent, green in the mulberry bush,
Riots with his tongue through the hush—
Sentinel of the grave who counts us all!”
—Allen Tate (1899–1979)
“A pragmatic race, the Japanese appear to have decided long ago that the only reason for drinking alcohol is to become intoxicated and therefore drink only when they wish to be drunk.
So I went out into the night and the neon and let the crowd pull me along, walking blind, willing myself to be just a segment of that mass organism, just one more drifting chip of consciousness under the geodesics.”
—William Gibson (b. 1948)
