Neon tetras are small, vibrant freshwater fish native to South America, highly popular in community aquariums due to their striking coloration.
Key features include:
-
Brilliant Coloration: They are famous for an iridescent neon-blue stripe running horizontally down their body alongside a vivid red stripe that covers the posterior half of their underbody.
-
Size: Growing to only about 1.5 inches (roughly 4 cm) in length, they are compact and streamlined.
-
Schooling Behavior: As peaceful schooling fish, neon tetras thrive best in groups of six or more, creating mesmerizing synchronized movements in planted tanks.
-
Habitat Preferences: They prefer well-planted aquariums with subdued lighting and soft, slightly acidic water that mimics their natural tropical rainforest environment.
