Description
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.[2][3]
Although capable of reaching up to 6 inches (15.24 cm), flying foxes have an average length of 4.7 inches (11.94 cm) and are frequent victims of stunting in the aquarium setting.[2][3]

Tank requirements
A 40-gallon or larger breeder tank lined with fine gravel or sand substrate is suitable for an average-sized flying fox fish. Being bottom-dwellers, the aquarium for flying foxes usually has broad-leaved plants, rocks, and driftwood to serve as hiding places. Because the flying fox is a known algae-eater, adequate lighting is preferred. Flying foxes can survive in aquarium water that has a pH of 6 to 7.5, a water hardness ranging from 2 to 12 dH, and temperatures kept at 23 to 27 °C (73 to 81 °F).[3][4]
Behavior
Flying foxes are generally compatible with acaras, angelfish, barbs, danios, eartheaters, gouramis, knifefish, loaches, tetras and rasboras. Aquarists may keep these fish alone or in schools, however a group of flying foxes may exhibit territorial behavior.
Life span
In the aquarium, flying foxes may live from eight to ten years.[4][5]
Diet
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.[2][3][4]
Breeding
Sex among flying foxes is difficult to determine, though as with most fish, mature females tend to be plumper and males more slender. Flying foxes are not known to breed in captivity.[3]
