Mystacoleucus Chilopterus

Datasheet

General Description

Mystacoleucus chilopterus, a species belonging to the Cyprinidae family under the order Cypriniformes, is characterized by specific physical features such as a concave distal margin on its anal fin, black margins on the anterior and distal regions of its dorsal fin, and black edging on its caudal fin. Individuals of this species also bear crescent-shaped black markings on some scales on the anterior part of their bodies. Mystacoleucus species are known to possess a predorsal spine directed towards the head, a trait shared with certain genera like Tor, Spinibarbus, and Paraspinibarbus.

Aquarium Setup

For an aquarium housing Mystacoleucus chilopterus, it is advisable to provide a setup mimicking its natural habitat. This species thrives in flowing, lowland river channels and forest streams with rocky and gravelly bottoms. The aquarium should ideally have ample water movement and be furnished with rocks and gravel to offer suitable substrates for the fish to explore and hide among. Further details on the recommended aquarium setup can be found in the accompanying table.

Behaviour

Mystacoleucus chilopterus is known to exhibit typical behavior for a pelagic species, preferring to occupy the mid-water column in its natural riverine environments. This species may demonstrate schooling behavior, especially in the presence of conspecifics or other compatible fish species. When kept in an aquarium setting, individuals of Mystacoleucus chilopterus should be provided with adequate space to swim freely, and the addition of suitable tankmates can help replicate its natural behavior more accurately.

Feeding and Diet

In terms of diet, Mystacoleucus chilopterus is an omnivorous species. While primarily feeding on small invertebrates and plant matter in the wild, individuals in captivity can be offered a varied diet that includes high-quality flake food, pellets, frozen foods like bloodworms and brine shrimp, as well as fresh vegetables. Providing a diverse diet is crucial to ensure proper nutrition and overall health for this species.

Reproduction & Dimorphism

Details regarding the specific reproductive behaviors and dimorphic characteristics of Mystacoleucus chilopterus are currently not explicitly outlined in the available information. It is advisable to refer to scientific studies or observations by experienced aquarists for more in-depth insights into the breeding habits, sexual dimorphism, and courtship behaviors of this species.

Habitat and Distribution

Mystacoleucus chilopterus is native to the middle Mekong basin in countries such as Laos and Thailand. It can be found in various river systems within these regions, including the Mun tributary drainage on the Khorat Plateau, the Chao Phraya and Mae Klong watersheds in Thailand, and potentially in Yunnan province, China. The species also reportedly occurs in the Malay Peninsula, although documented records are limited. Habitats preferred by Mystacoleucus chilopterus include flowing lowland river channels and fast-moving forest streams characterized by rocky and gravelly substrates.
