Pseudohomaloptera Sexmaculata

Datasheet

General Description

The Pseudohomaloptera Sexmaculata, previously known as Homaloptera sexmaculata, belongs to the family Balitoridae and is classified under the Cypriniformes order. It showcases a relatively elongated body, narrow caudal peduncle, and dark body coloration with distinctive saddle-shaped markings along its dorsal surface. This species, commonly referred to as a gecko loach, is specialized for life in fast-flowing waters, with flattened bodies and horizontally extended paired fins allowing them to cling tightly to solid surfaces.

Aquarium Setup

For optimal care of Pseudohomaloptera Sexmaculata, a tank size of at least 96 litres is recommended. A clean and well-oxygenated environment is crucial, necessitating an oversized filter with a turnover rate of 10-15 times per hour. The base substrate can be gravel, sand, or a combination of both, complemented by water-worn rocks, pebbles, and driftwood. Aquatic plants like Microsorum, Crinum, and Anubias spp. can be incorporated into the tank decor, providing resting spots for the loaches. The species thrives in stable water conditions and feeds on biofilm, making a biologically mature setup essential.

Behaviour

Pseudohomaloptera Sexmaculata is not aggressive but can be reclusive, preferring suitable tankmates like Danio, Devario, Rasbora, and certain catfish species. They are not particularly territorial towards conspecifics and tend to thrive in groups, recommending the purchase of four or more individuals. Balitoridae loaches exhibit unique behaviors suited for life in swift currents, utilizing their sucking cup-like bodies to traverse rocks and solid surfaces.

Feeding and Diet

Specialized grazers, Pseudohomaloptera Sexmaculata feed on biofilm, small crustaceans, insect larvae, and invertebrates. While they may accept sinking dried foods, a diet comprising live or frozen Daphnia, Artemia, and bloodworm is crucial for their health. Algae growth on surfaces within the tank provides additional sustenance. To support weakened specimens, a consistent and nutritious food source is vital in the absence of competitors.

Reproduction & Dimorphism

Information on the reproduction of Pseudohomaloptera Sexmaculata is unrecorded. Sexually mature females are typically larger and fuller-bodied than males, showcasing subtle sexual dimorphism.

Habitat and Distribution

In their natural habitat, Pseudohomaloptera Sexmaculata inhabits swiftly-flowing streams with clear, oxygen-saturated water, gravitating towards gravel, rock, and biofilm-covered substrates. Their distribution spans regions within Thailand, specifically in the Chao Phraya and Mae Klong watersheds. The species is found alongside various other fish species in these habitats, displaying preferences for specific substrates and environmental conditions.
