Long-fin Serpae Tetra
The long-fin serpae tetra has the same bold red and black colors as the parent serpae tetra, but these aquarium fish have been bred to develop long, flowing fins. Usually harmless, these fish tend to chase around smaller peaceful fish. The long-fin serpae tetra is also called the long-fin red minor.

The long-fin serpae tetra adds a striking visual element to my tank. The red and black coloring is vivid, and the long fins move beautifully. I keep them with larger, calm fish, and they don’t cause much stress. Just make sure to avoid very small species.
