Black Neon Tetra vs Green Neon Tetra: Differences, Similarities, and Care Tips

Black neon tetras (Hyphessobrycon herbertaxelrodi) and green neon tetras (Paracheirodon simulans) are both popular choices among fishkeepers due to their small size, colorful appearance, and peaceful nature. However, there are some differences between the two species that are important to consider when deciding which one is right for your aquarium.

In this article, we'll take a closer look at the differences and similarities between black neon tetras and green neon tetras, as well as provide some care tips to help you keep these beautiful fish healthy and happy in your tank.

Black Neon Tetras

Black neon tetras are small, peaceful fish that are native to the upper Orinoco and Negro rivers in South America. They are known for their distinctive black coloration with a bright neon blue stripe running down their sides. Black neon tetras are often confused with another species called the black skirt tetra (Gymnocorymbus ternetzi), but they can be distinguished by the presence of a small black spot on the base of their tail fin, which black skirt tetras do not have.

Green Neon Tetras

Green neon tetras (Paracheirodon simulans) are small, colorful fish that are native to the Amazon Basin in South America. They are known for their bright green coloration with a neon blue stripe running down their sides. Green neon tetras are often confused with another species called the cardinal tetra (Paracheirodon axelrodi), but they can be distinguished by the presence of a small black spot on the base of their tail fin, which cardinal tetras do not have.

Differences between Black Neon Tetras and Green Neon Tetras

One of the most obvious differences between these two species is their coloration. As their names suggest, black neon tetras are black with a bright neon blue stripe running down their sides, while green neon tetras are green with a neon blue stripe.

Another difference is their natural habitat. Black neon tetras are native to the upper Orinoco and Negro rivers in South America, while green neon tetras are native to the Amazon Basin.

In terms of size, black neon tetras are slightly smaller than green neon tetras, reaching a maximum size of about 1.5 inches (3.8 cm) compared to 2 inches (5 cm) for green neon tetras.

Similarities between Black Neon Tetras and Green Neon Tetras

Despite their differences, black neon tetras and green neon tetras do have some similarities. Both species are peaceful and do well in a community tank with other small, peaceful fish. They are also both omnivores, meaning they will eat a variety of foods including flakes, pellets, frozen or live insects, and vegetables.

Both species also have similar care requirements, including a preference for a well-planted tank with a pH between 6.0 and 7.5 and a temperature between 73 and 81 degrees Fahrenheit (23-27 degrees Celsius). They also both prefer a tank with some hiding spots, such as caves or plants, and do well in schools of at least six individuals.
