Behaviour:
The Cyclocheilichthys heteronema species is characterized by its peaceful nature, making it suitable for community tanks; however, caution is advised when selecting tankmates to avoid intimidating or outcompeting this fish. Keeping them in groups of at least four can help reduce nervousness, and they have been successfully housed with small, peaceful cyprinids and loaches in aquariums. Their gregarious nature suggests they thrive best in the presence of conspecifics to feel secure and exhibit natural behaviors. In their native habitat, they coexist with species like Rasbora daniconius, Nemacheilus pallidus, and Trichogaster spp., highlighting their adaptability to group settings.
Feeding and Diet:
Cyclocheilichthys heteronema is considered a micropredator, foraging for small insects, crustaceans, and worms in the substrate. To maintain optimal health in captivity, offer a varied diet including live and frozen foods like bloodworms, Tubifex, Daphnia, and Artemia, alongside high-quality sinking prepared foods. Providing daily meals that simulate their natural feeding habits will help these fish thrive in an aquarium setting.
Reproduction & Dimorphism:
There is limited information on the breeding of C. heteronema in aquariums. Mature females may exhibit a rounder belly compared to males, which could indicate sexual dimorphism. Further research is needed to understand the reproductive behavior and differences between male and female individuals of this species.
Habitat and Distribution:
Cyclocheilichthys heteronema is distributed across Southeast Asia, ranging from Myanmar to the Greater Sunda Islands. They are commonly found in river basins, lakes, and reservoirs, with a notable presence in Peninsular Malaysia. Their ability to adapt to various water bodies and habitats suggests they may represent a group of closely related taxa. In the wild, they inhabit deeper waters but may move to shallower zones during specific periods, such as the wet season when they venture into flooded areas.
