True Flying Fox (Epalzeorhynchos kalopterus)

The True Flying Fox is a somewhat shy but stunning fish that is best kept as a single specimen in an aquarium.

These fish are somewhat aggressive to their own kind and other similar shaped fish such as the Rainbow and Red-Tailed Shark as well as Garra species, especially the very similar-looking False Siamese Algae Eater (Garra cambodgiensis).

While it is possible to keep more than one True Flying Fox In an aquarium, it comes with some risks. Due to their territorial temperament, there's a high possibility that these fish will fight unless they have a significant amount of space and hiding places.

The True Flying Fox is generally compatible with most other types of aquarium fish, including Loaches, Barbs, Danios, Tetras, and even very small Rasboras, making them excellent community aquarium members.

The True Flying Fox has an elongated body and a flat stomach. The lower part of its body has a yellowish-white hue, and its dorsal region has a colouration ranging from olive to dark brown. A brownish-black stripe runs from its mouth to the caudal fin and on top of that is a gold-coloured stripe. The True Flying Fox\'s have a reddish iris, and its anal, dorsal and ventral fins consist of a translucent front with a thick black band along the edge.

The True Flying fox is primarily an algae eater; however, they will also readily accept high quality dried food such as flakes and granules and algae wafers.

If you want your fish to develop its best condition and colours, you should offer them regular meals of small frozen or live food such as bloodworm, tubifex or chopped white worms.

It would be most beneficial if you also included some vegetable matter into their diet in the form of Zucchini, cucumber, broccoli and lettuce.
