The Serpae tetra is a species of freshwater fish belonging to the characin family. It has a flat and tall body and a bright redish-brown color. The fish can reach up to 1.5 inches long, and prefers a pH range of 5 to 7.8, a temperature range of 72°F – 79°F (22°C – 26°C), and a hardness range of 10° to 25° dH. The species’ color can range from olive-brown to fiery scarlet-hued, and can change throughout the fish’s life.

The serpae tetra is omnivorous and will eat both plant and animal food in the aquarium. It is best suited for feeding small fish such as shrimp, bloodworm, or brine shrimp, but it will also accept flake food, pellet food, or live fish food.
