Herbivore. It is a good algae eater in aquariums (considered by many to be the very best), which also eats black beard algae. Also gladly eats live and frozen food in aquariums, vegetable food is necessary. Spawn behavior not known. The Siamese flying fox is peaceful towards other species, but somewhat aggressive and territorial towards others of the same species. Given that the aquarium is not too small, one can keep a small group of them in the same aquarium without major problems. It is also good to keep in communitytanks. The aquarium should be decorated with plants (it does not eat plants) and some hiding places in the form of roots. Fine sand is suitable as a bottom material. The water must be oxygen-rich. You can't see a difference between females and males. This species is often mixed up with Epalzeorhynchos kalopterus. On the Siamese flying fox, the fins are translucent, in addition, it has a pair of barbels on the upper lip, E.kalopterus has two pairs. Another characteristic is that the part of the dark longitudinal band that stretches throughout the body all the way to the the caudal fin of E.calopterus is wider and darker than that of C. oblongus . Presumably this species will shortly change its name to Crossocheilus langei as it is assumed to look completely different and has for the most part never been imported into the aquarium hobby.
