Flying Fox Care Guide
Epalzeorhynchos kalopterus · Freshwater Fish
What Flying Fox look like
Epalzeorhynchos kalopterus, commonly known as the Flying Fox, exhibits a fusiform body shape that can reach a maximum adult size of approximately 12 inches (30 cm). The species is characterized by a deep gold dorsal region that transitions to a pale ventral surface, creating a striking contrast. A prominent feature is the thick, solid black horizontal stripe that runs laterally along the body, which is particularly vivid and serves as a key identification trait. The fins are adorned with distinct, thick black and white bands that are perfectly parallel within the fin membranes, enhancing its visual appeal. Sexual dimorphism is subtle, with males typically exhibiting slightly more vibrant coloration and larger dorsal fins during breeding periods. Defensive adaptations include a streamlined body that allows for rapid escape from predators, and the species possesses a lateral line system that aids in detecting movement and vibrations in the water column.
Behavior & temperament
The Flying Fox is a social fish that thrives in groups, often forming loose schools in its natural habitat. It predominantly occupies the mid to upper levels of the water column, displaying a pelagic dwelling behavior. Breeding occurs through egg scattering, where females release eggs into the water column for fertilization by males, typically during the rainy season. The species is generally peaceful, exhibiting a calm temperament, although it may display territorial behaviors during breeding or when kept in smaller aquaria. In captivity, it is advisable to maintain them in groups to promote natural social interactions and reduce stress.
Diet & feeding
In the wild, the Flying Fox is an omnivore, feeding on a varied diet that includes algae, plant matter, and small invertebrates. In captivity, it requires a balanced diet consisting of high-quality flake food, algae wafers, and occasional live or frozen foods to ensure optimal health and coloration.
