Black Phantom Tetra
Hyphessobrycon megalopterus is a popular tetra species. Males are gray to black and develop large, showy fins that they flare up while sparring to impress females; the ladies are smaller but equally as beautiful with a reddish-gray body colour and bright reds in their fins. Watching the males “dance” as they display is incredible! They are quite hardy and pair well with most other peaceful fishes.
These are young adults around 1″ long.

The Black Phantom Tetras are vibrant and active. I noticed the males flaring their fins during the day, which is very entertaining. They’ve adapted well to my 10-gallon tank with other peaceful community fish. Easy to care for and look great in a group.

They arrived healthy and are now swimming around happily. The color contrast between males and females is striking. I’ve kept them with neon tetras and they don’t seem to compete for space.

Great addition to my aquarium. The males display their fins beautifully, especially in the evening. They’re hardy and don’t require much maintenance. I’d recommend them to anyone looking for colorful, active tetras.
