Crossocheilus Reticulatus

Datasheet

General Description

Crossocheilus Reticulatus, commonly known as the reticulated flying fox, is characterized by its silvery body, dark-edged scales, and dark caudal peduncle blotch. Belonging to the Cyprinidae family, they possess 8 branched dorsal fin rays, immobile rostral lobes, and lack a dorsal spine. Their upper and lower lips are not connected, with the upper lip attached to the lower jaw via a thin membrane.

Aquarium Setup

To maintain Crossocheilus Reticulatus, it is advisable to replicate a flowing river or stream environment in a tank. The setup should entail substrates of rocks, gravel, and water-worn boulders, with driftwood branches for shelter and breeding grounds. Plants like Microsorum, Bolbitis, or Anubias species can be attached to the decor, complemented by bright lighting to encourage algae growth for grazing. Clean water with high oxygen levels and water movement are essential for their well-being.

Behaviour

Crossocheilus Reticulatus are generally peaceful and thrive in groups of six or more to establish a pecking order. Shoaling by nature, they exhibit interesting behavior when interacting within the group. They may become shy or skittish if kept alone or in small numbers, preferring the company of their own kind or compatible species.

Feeding and Diet

In their natural habitat, Crossocheilus species are aufwuchs grazers, feeding on algae, diatoms, and phytoplankton. Their diet in captivity should consist of high-quality dried foods with added Spirulina, supplemented with fresh vegetables like shelled peas, blanched courgette, spinach, and fruits. They also forage on biofilms that accumulate on rocks in the aquarium.

Reproduction & Dimorphism

Reproduction of Crossocheilus Reticulatus has not been recorded in aquarium settings. Sexually mature females tend to have a thicker body compared to males, making it challenging to differentiate sexes based on external characteristics, particularly in younger specimens. The species is known to undergo seasonal reproductive migrations in their natural habitat.

Habitat and Distribution

These fish are commonly found in the Chao Phraya river drainage in central Thailand and the Mekong basin across Thailand, Cambodia, Laos, Vietnam, and southern China, particularly Yunnan province. In their natural habitat, they inhabit flowing streams with substrates of boulders, pebbles, gravel, and sand, frequenting areas with submerged driftwood or tree roots. The clear, shallow waters allow sunlight penetration, fostering the growth of biofilm that serves as a food source for the fish.
