Real-world information
Neon tetras are native to backwater and clear water streams in southeastern Colombia, eastern Peru, and western Brazil, living in the Amazon river. Neon tetras are a popular aquarium fish, mainly because of its appealing coloration. It has a light-blue back that meets a silver-white abdomen, with a red and blue stripe in between them. It is however, transparent. During the night, when the neon tetra is inactive, it loses its red and blue stripe, which turns silver. There is a slight difference between male and female neon tetras. The males have a straight red-blue stripe while females have a slightly crooked stripe, because of their rounder body shape. Neon tetras can be afflicted by "Neon Tetra Disease" (or NTD), which is incurable. It involves the loss of coloration in the bodies as well as restlessness.
