Neon tetras are small, brightly colored freshwater fish that are popular in the aquarium trade. As their name suggests, they are known for their vibrant neon blue and red stripes that run along their bodies. The blue stripe is located on the upper half of their body, while the red stripe is located on the lower half. The rest of their body is typically silver.
The neon blue color of the fish is due to a protein called reflectin, which reflects blue light. The red color, on the other hand, is due to a pigment called astaxanthin. When the light hits the fish, the blue and red colors are reflected back, creating a striking and beautiful appearance.
It is worth noting that the color of neon tetras can vary depending on their environment and diet. In some cases, the blue stripe may appear more greenish, or the red stripe may appear more orange. This can be due to a variety of factors, such as water quality, lighting, and the type of food they are fed.
Overall, neon tetras are a stunning addition to any aquarium, and their bright colors can add a pop of color to any room. They are also relatively easy to care for, making them a popular choice for beginner fish keepers.
