The green neon tetra (Paracheirodon simulans) is a small, freshwater fish species that is closely related to the more well-known neon tetra (Paracheirodon innesi). It is native to the blackwater tributaries of the Amazon River in South America and is a popular choice for aquarium enthusiasts due to its beautiful green and blue coloration.
Green neon tetras are small fish, growing up to about 1 inch in length. They have a slender, streamlined body with a bright greenish-blue stripe running horizontally along their sides. The rest of their body is iridescent silver or white.
In the wild, green neon tetras inhabit densely planted, slow-moving streams and tributaries. In the aquarium, they require similar conditions with soft, slightly acidic water and plenty of plants to provide cover and hiding places.
Green neon tetras are peaceful and can be kept in a community aquarium with other small, non-aggressive fish species. They are omnivorous and will readily accept a variety of foods, including flakes, pellets, frozen or live foods such as brine shrimp, bloodworms, and daphnia.
Overall, the green neon tetra is a beautiful and peaceful fish species that is relatively easy to care for and suitable for aquarium enthusiasts of all levels.
