"Neon tetras get their name from the beautiful blue metallic line on their bodies. Although they're shy, gentle fish, surprisingly they're related to the piranha, though very distantly. They have very sharp and narrow teeth, an odd contrast to their beauty. They are delicate fish who tend to be very sensitive to the cleanliness and temperature of water."

When donating to the museum, Blathers will say the following:

"Hoo! Wonderful! The neon tetra is truly a marvel of the tropical-fish world. Just look at how tiny it is! And how very filled with...neon! I imagine its environment must be just as flashy as it is for it to have developed such colors. I wonder how flashy I might be, had I been raised somewhere even half as vibrant? "

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.
