Neon Tetra
The Neon Tetra (Paracheirodon innesi) is a species of fish. A variety of Characidae (Tetra) which is mostly transparent, apart for an iridescent blue/green horizontal stripe along each side of the fish, from nose to the front part of the tail (the tail and fins are virtually invisible).
When kept in an aquarium
Timid unless hungry. Mid-level feeder. Best kept in a group of 8 or more for the "shoaling" effect when they move around the tank. Their colour and the iridescent stripe become dim at night, and they can be virtually invisible after a period of darkness.
