Acanthopsoides Sp. 'A02'

Datasheet

General Description

Acanthopsoides spp., commonly known as "dwarf horse-face loaches," are closely related to the horse-faced loaches of the genus Acantopsis. This genus comprises five species, with some potentially yet to be identified. They have distinct characteristics such as a slender body, bifid suborbital spines, and a symmetrical, emarginate caudal fin. Acanthopsoides spp. exhibit a basic shared patterning with blotches along the body and fins, aiding in identification. They are part of the Cobitidae family, characterized by concealed but erectable sub-ocular spines as a defense mechanism.

Aquarium Setup

A suitable aquarium setup for Acanthopsoides requires a soft, sandy substrate to accommodate their burrowing behavior, preventing stress and injuries. Decorate the tank with water-worn rocks, driftwood, and leaf litter to create hiding spots and shaded areas. Maintain dim lighting unless growing plants, and avoid high flow rates while ensuring adequate oxygenation. Cover the tank securely to prevent jumping, a behavior common among loaches.

Behaviour

Acanthopsoides are peaceful creatures that exhibit gregarious behavior, preferring to be kept in groups of six or more. They are compatible with peaceful tankmates, particularly small, schooling cyprinids inhabiting the upper water column. The presence of such tankmates can help reduce their timidity, as Acanthopsoides interpret the absence of upper-dwelling fishes as a sign of impending danger in their natural habitat.

Feeding and Diet

Acanthopsoides spp. primarily feed on insect larvae, small crustaceans, and similar food sources sifted from the substrate through their gills. Offer a varied diet comprising sinking dried foods, live, and frozen options such as Artemia, Tubifex, Daphnia, and bloodworms to ensure nutritional balance. Adequate feeding requirements contribute to the overall health and vitality of these loaches.

Reproduction & Dimorphism

While Acanthopsoides have not been extensively bred in aquarium settings, successful spawns have been documented with proper conditions. Male Acanthopsoides exhibit enlarged pectoral fins with breeding tubercles, while females are typically heavier and slightly larger. Detailed observation and providing suitable breeding conditions may facilitate successful breeding attempts in captivity.

Habitat and Distribution

Acanthopsoides spp. predominantly inhabit flowing, clear water river channels with sandy, gravelly, or muddy substrates. They live in groups of varying sizes based on the species and are commonly found in regions like Thailand or Peninsular Malaysia. Their natural habitat influences their behavior, feeding habits, and reproductive patterns in an aquatic environment.
