General Description
The Nemacheilus Troglocataractus, belonging to the Nemacheilidae family within the Cypriniformes order, exhibits troglomorphic traits with depigmented bodies and often lacks visible eyes. This species is protected under Thai national law and is considered critically endangered due to its restricted distribution within subterranean cave systems.
Aquarium Setup
The specific tank setup requirements for Nemacheilus Troglocataractus are not provided in the available information. For more details on the aquarium setup, please refer to the relevant table.
Behaviour
In aquarium environments, these loaches show territorial behavior, with instances of aggression observed among individuals. Dominant fish display a distinctive swimming pattern characterized by a zig-zag motion, combined with lateral and ventral shoving and biting behaviors towards tank mates.
Feeding and Diet
Although unconfirmed, the common diet of Nemacheilus Troglocataractus likely consists predominantly of benthic invertebrates, reflecting its natural feeding behaviors in the wild.
Reproduction & Dimorphism
Details on the reproduction of Nemacheilus Troglocataractus remain unrecorded, both in aquaria and in its natural habitat. Observations in other cave-dwelling fish species suggest that they may follow a life cycle adapted for subterranean environments, producing fewer but larger eggs that hatch into relatively well-developed fry.
Habitat and Distribution
Nemacheilus Troglocataractus is exclusively known to inhabit a single cave system near Nam Tok Sai Yok Noi in Thailand. This cave system, part of the Khwae Noi river basin, provides a subterranean habitat with slow water flow, composed of bedrock and gravel substrates, where the species coexists with other cave-adapted fish species.
Etymology
The genus name Nemacheilus is derived from Greek terms meaning 'thread' or 'filament' and 'lip,' referencing certain physical features common in this genus. The specific epithet Troglocataractus combines Greek and Latin words denoting 'hole' and 'waterfall,' respectively, linking the species to the type locality and cave name translations.
Distribution
The range of Nemacheilus Troglocataractus is restricted to the cave system Tham Sai Yok Noi in Thailand, presenting challenges for researchers due to high carbon dioxide levels preventing extensive exploration. The species' limited distribution highlights its vulnerability and critical conservation status.
