General Description
Body coloration in Acrochordonichthys Gyrinus species varies individually but typically includes shedding of skins resulting in a paler appearance post-moulting. Belonging to the A. ischnosoma group, this species features distinguishable physical characteristics such as a slim caudal peduncle, narrow head, and specific vertebral counts. Noteworthy adaptations include the ability to secrete a milky substance for defense and a unique gill opening aiding in locomotion.
Aquarium Setup
Maintaining Acrochordonichthys Gyrinus requires a clean, well-oxygenated environment with ample dissolved oxygen content. A river tank manifold or oversized filter is recommended for efficient water filtration. The tank should contain fine gravel or sand substrate, water-worn rocks, pebbles, and optional leaf litter. Incorporating aged driftwood and hardy aquatic plants like Java fern is suggested. Stable water chemistry is crucial, warranting regular 30-50% partial water changes weekly.
Behaviour
These catfish species are sedentary and prefer targeted feeding, accepting live or frozen invertebrates like chronomid larvae and small earthworms. They are not suitable for communal setups due to their predatory nature. However, they can coexist with larger, non-aggressive fish species in spacious tanks with flowing water conditions.
Feeding and Diet
Acrochordonichthys Gyrinus are ambush predators consuming invertebrates like chronomid larvae without the need for live fish in captivity. Direct feeding stimulation may be necessary in the aquarium setting due to their sedentary behavior, making them poor competitors for food resources.
Reproduction & Dimorphism
Limited information is available on the breeding behavior of Acrochordonichthys Gyrinus in captivity, and their natural reproductive habits remain largely undocumented. Sexual dimorphism in males is distinguished by the position and structure of the genital papilla compared to females.
Habitat and Distribution
Endemic to the Yom River in Phitsanulok Province, northern Thailand, Acrochordonichthys Gyrinus inhabits fast-flowing forest streams with sandy or rocky substrates and submerged driftwood or rocks. The species appears to be predominantly nocturnal based on observations in both captive and wild environments.
