General Description
The Butterfly Loach, scientifically known as Beaufortia Kweichowensis, is a member of the Gastromyzontidae family and is native to the Xi Jiang system in southern China. This species has a maximum size of 7.5cm and is recognized for its specialized morphology adapted for life in fast-flowing waters.
Aquarium Setup
To create a suitable environment for the Butterfly Loach, it is essential to maintain clean and well-oxygenated water with a turnover rate ideally between 10-15 times per hour. Using an oversized filter, powerheads, and airstones is recommended. The tank should have gravel, sand, or a mixture of both with water-worn rocks and pebbles. Aged driftwood can be added, and aquatic plants like Microsorum and Anubias spp. can provide cover. The water conditions should have a pH of 6.5-8.0, hardness of 36-268ppm, and a temperature range of 16-24°C.
Behaviour
Butterfly Loaches are generally peaceful, but their territorial nature can lead to conflicts with conspecific males and similar-looking species. Males exhibit bolder behaviors, while females tend to congregate in quieter areas of the tank. It is recommended to keep these loaches in groups of six or more to observe their most interesting behaviors.
Feeding and Diet
In the wild, Butterfly Loaches consume benthic algae and microorganisms from solid surfaces. In captivity, they accept dried foods, live or frozen bloodworms, and a diet rich in vegetables and Spirulina. Providing a mature aquarium with algae-covered rocks is beneficial, and periodic water changes are essential for their well-being.
Reproduction & Dimorphism
There is limited information on the reproduction of Butterfly Loaches in aquaria. The most noticeable difference between males and females is in the shape of their head and body when viewed from above. Females are broader and heavier, while males are slimmer with a squarer snout.
Habitat and Distribution
Butterfly Loaches inhabit shallow, fast-flowing, oxygen-rich waters in headwaters and minor tributaries with substrates of rocks, sand, and gravel. They are native to the Xi Jiang system in southern China, but due to pollution in the region, the water quality has been affected. Guangdong Province is a significant hub for the export of ornamental fish, including species that share similar habitats with the Butterfly Loach.
