General Description
S. deansmarti is a species of blind loach belonging to the Nemacheilidae family within the order Cypriniformes. Endemic to the Tham Phra Sai Ngam cave system in Thailand, these troglomorphic fishes exhibit morphological adaptations to their subterranean existence, with some specimens lacking externally visible eyes and all individuals being entirely depigmented.
Aquarium Setup
The specifics of tank setup for S. deansmarti are not provided; however, as a protected species in Thailand, it is illegal to remove them from their natural habitat.
Behaviour
This species, like other troglobitic fishes, may display behaviors adapted to their unique ecology, such as low population size, restricted distribution, and a lack of environmental cues. They are often found in flowing streams near waterfalls or in cave systems, with some individuals being completely blind and depigmented.
Feeding and Diet
While the exact diet of S. deansmarti is unconfirmed, it is likely that they primarily consume benthic invertebrates and zooplankton present in their habitat.
Reproduction & Dimorphism
Male S. deansmarti exhibit sexual dimorphism, with poorly-developed suborbital flaps that are absent in females. Precise details regarding their reproductive behavior are not provided in the information.
Habitat and Distribution
The species S. deansmarti is endemic to the Tham Phra Sai Ngam cave system in Thailand. This limestone cave system is approximately 1.7 km long and includes a subterranean stream with variable flow, where the fish can be found in stagnant pools during parts of the year.
