These tetras are vibrant and active. The large fins make them stand out in the tank. I kept a school of six and they swim together nicely. Easy to care for and adapt well to my tank conditions.

Great addition to my community tank. They are peaceful and don’t bother other fish. The color is deep black with silver highlights, and they look stunning in a well-maintained aquarium.

I’ve had them for over a year and they’re still active and healthy. They thrive in a moderate temperature range and eat a variety of foods. The school behavior is very natural and entertaining.
