About the African Red-Eyed Tetra
The African Red-Eyed Tetra, scientifically known as Arnoldichthys spilopterus, is a lively freshwater fish originating from the rivers of West Africa. Known for its vibrant coloration and schooling behavior, this species adds dynamic movement and a splash of red to aquariums.
Characterized by a sleek, elongated body, the African Red-Eyed Tetra displays a striking contrast between its silvery base color and the distinctive red coloring around its eyes and adipose fin. The red eyes provide a captivating focal point, making these tetras visually appealing in a well-lit aquarium.
In their natural habitat, African Red-Eyed Tetras inhabit slow-moving rivers and streams with dense vegetation. Replicating this environment in captivity involves providing a well-planted aquarium with open swimming areas. These tetras are social and thrive when kept in groups, making them an excellent choice for a community aquarium.
Feeding the African Red-Eyed Tetra is straightforward, as they are omnivores. They accept a variety of foods, including high-quality flakes, pellets, live or frozen brine shrimp, and daphnia. Offering a diverse diet enhances their coloration and overall health.
African Red-Eyed Tetras are known for their active and schooling behavior, creating a dynamic display in the aquarium. Their schooling instinct provides not only a visually appealing sight but also a sense of security for the individual tetras.
