The flying fox (Epalzeorhynchos kalopterus) is a Southeast Asian species of freshwater fish in the family Cyprinidae. It is commonly kept in the aquarium trade. Among other foods, it is known to eat green algae. It is sometimes mistakenly referred to as the Siamese algae eater.

Appearance

The flying fox fish has a characteristic long body with a flat abdominal area. Its dorsal area has a coloration ranging from olive to dark brown. The lower half of its body has a yellowish white hue. A brownish-black line runs from its mouth to the caudal fin. On top of this distinctive black line is a gold-colored stripe. The eyes of a flying fox may have a reddish iris. Its dorsal, anal and ventral fins consist of a transparent front with a thick black band along the edge.

Diet and Nutrition

Mainly algae eaters, flying foxes also eat flakes, wafers and tablets. Vegetables such as spinach, zucchini and lettuce, as well as live planarians, tubifex worms, crustaceans and other aquatic insects, are excellent staples for these omnivores. They do not consume red algae.

Mating Habits

Sex among flying foxes is difficult to determine, though as with most fish, mature females tend to be plumper and males more slender.

Population

In captivity

Flying foxes are not known to breed in captivity. In the aquarium, flying foxes may live from eight to ten years.
