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.

In the home aquarium, the True Flying Fox will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.
