Balitoropsis Zollingeri

Datasheet

General Description

The Balitoropsis Zollingeri, commonly known as "lizard loaches," are members of the Balitoridae family, characterized by their specialized morphology for life in fast-flowing waters. These fish have horizontally extended fins, flattened bodies, and a depressed belly, enabling them to cling tightly to solid surfaces using their powerful sucking cup. Balitoropsis Zollingeri typically reach a maximum size of 7.0cm and make intriguing aquarium inhabitants with their unique behavior and appearance.

Aquarium Setup

Setting up an aquarium for Balitoropsis Zollingeri requires clean and well-oxygenated water, ideally maintained with an over-sized filter to achieve a turnover of 10-15 times per hour. The tank should contain a substrate of gravel, sand, or a mixture of both, along with water-worn rocks and pebbles. Incorporating driftwood roots, branches, and aquatic plants like Microsorum, Crinum, and Anubias spp. provides suitable enrichment. Additionally, ensuring stable water conditions and promoting the growth of aufwuchs on most surfaces, except the viewing pane, is crucial for the well-being of these fish.

Behaviour

Balitoropsis Zollingeri are not aggressive fish, but their unique requirements in terms of suitable tankmates must be considered when selecting companions. These species are often found living in aggregations in nature, showcasing their best behavior when kept in groups of six or more. When kept individually or in small numbers, they may display less bold behavior, being among the more retiring members of their genus. Interactions with other fish species, especially loaches and some catfish, should be monitored to prevent any harmless squabbles.

Feeding and Diet

Balitoropsis Zollingeri are specialized grazers, feeding on biofilm, small crustaceans, insect larvae, and other invertebrates in their natural habitat. In captivity, they may accept sinking dried foods; however, a diet rich in live or frozen options like Daphnia, Artemia, and bloodworm is essential for their optimal health. These fish benefit greatly from having a tank with algae growth and other aufwuchs to mimic their natural feeding behavior. It's crucial to provide continuous access to suitable foods, particularly for weakened specimens, to aid in their recovery.

Reproduction & Dimorphism

There is limited recorded information about the reproduction of Balitoropsis Zollingeri, both in natural environments and aquarium settings. Sexually mature females are typically slightly larger and fuller-bodied compared to males, showcasing subtle sexual dimorphism. Understanding the breeding behavior and requirements of these fish is essential for successful captive reproduction efforts.

Habitat and Distribution

Balitoropsis Zollingeri are obligate dwellers of swiftly-flowing streams and headwaters with clear, oxygen-saturated water. They primarily inhabit riffles and runs in these habitats, showing a preference for shallower zones with substrates composed of gravel, rocks, or boulders covered in biofilm. These fish have been documented in various regions, including Indonesia, Sumatra, Borneo, Malaysia, Thailand, and parts of Cambodia and Laos, indicating a wide distribution across Southeast Asia.
