What African Red Eyed Tetra look like
Arnoldichthys spilopterus, commonly known as the African Red Eyed Tetra, exhibits a medium-sized, laterally compressed body that typically reaches a maximum adult size of 3-4 inches (7.5-10 cm). The species is characterized by its strikingly vivid red upper half of the eye, which serves as a key distinguishing feature. The body is adorned with large, iridescent scales that exhibit a green-gold sheen, particularly prominent along the flanks. Males are noted for their multi-colored anal fin, which displays a combination of red, yellow, and dark banding, contributing to sexual dimorphism within the species. Defensive adaptations include a streamlined body shape that allows for quick evasive maneuvers in the water column. Additionally, the presence of a lateral line system aids in detecting movement and vibrations in the surrounding environment, enhancing their ability to evade predators.
Behavior & temperament
The African Red Eyed Tetra is a social fish typically found in small to medium-sized schools, demonstrating a preference for a hierarchical social structure where dominant individuals may assert themselves over subordinates. They are primarily pelagic, occupying the mid to upper levels of the water column, and exhibit a peaceful temperament, making them suitable for community aquariums. Breeding behavior is characterized by egg scattering, where females release eggs in open water, allowing for fertilization by males. Their gentle nature and schooling behavior contribute to a dynamic and visually appealing display in an aquarium setting.
Diet & feeding
In the wild, Arnoldichthys spilopterus is an omnivore, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they thrive on high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia, as well as vegetable matter to ensure a balanced diet.
