Flying Fox

Epalzeorhynchos kalopterus

The Flying fox is often sold as an algae eater, and whilst it will eat some algae, it is probably sold as such in confusion with the similar Siamese Flying fox (Crossocheilus siamensis) which is indeed a very good algae eater. Flying foxes will not eat thread (hair) algae, and are of limited use as an algae eater. In the aquarium Flying foxes can be territorial and will cause trouble for fish which are not robust. Since they are similar species, sharks (labeo sp.), denisons barbs, silver sharks, and algae loaches are particular targets for squabbles. However, Flying foxes are good additions to lively communitys of medium sized fish such as barbs, rainbowfish, and cichlids. Vegetable matter should make up part of the fishes diet, although they will not harm robust plants, as well as regular sinking foods and some meaty foods. Soft, acidic water is prefered but the fish is adaptable enough to adjust to harder water. An easy to keep fish, but not suited to communities of smaller, peaceful fish. Best kept singly.

Family Cyprinidae (Carps & Minnows) | Synonyms Barbus kalopterus | Origin Asia: Indonesia, Malaysia, Thailand | Natural Water Conditions pH 6.5-7, soft | Natural Habitat Flowing waters
