Behaviour
The Chameleon Loach can exhibit belligerent behavior and should not be housed with significantly smaller fish due to potential intimidation and its sometimes very active nature. Slow-moving, long-finned species such as ornamental bettas, guppies, and certain cichlids should also be avoided to prevent fin nipping. Suitable tankmates include fast-moving, pelagic cyprinids like Devario, Rasbora, and Puntius, while in larger tanks options like Barilius, Luciosoma, Balantiocheilos, and Barbonymus are viable. These loaches are social and should be kept in groups of at least 5-6 individuals, preferably 10 or more, to prevent aggression and promote natural behavior. Regular contact with conspecifics is essential for their well-being, as they exhibit several behavioral rituals best observed in a group setting.
Feeding and Diet
The Chameleon Loach, like Syncrossus species, is primarily carnivorous but can consume plant matter when available. Their diet should include a variety of quality dried foods, live or frozen offerings like bloodworms and Artemia, as well as fresh fruits and vegetables such as cucumber and spinach. Additionally, chopped earthworms can provide a protein source, and gel-based homemade foods are highly recommended. While they may consume aquatic snails, they should not be relied upon to control infestations. Once acclimated, they are bold feeders and will readily accept a diverse diet.
Reproduction & Dimorphism
Breeding the Chameleon Loach in aquarium settings seems to be uncommon, suggesting they are likely seasonal, migratory spawners in their natural habitat. Adult females are expected to be stockier and potentially larger than males; however, other visual differences between the sexes have yet to be documented extensively.
Habitat and Distribution
Native to Thailand, the Chameleon Loach was described in the Tadi stream in Nakhon Si Thammarat province and has been documented in regions such as Trang province, the Ataran River, the Chao Phraya system, and central and western Thailand. Threats to wild populations include habitat alteration due to damming, pollution, and collection for the aquarium trade. Their decline has been reported, prompting conservation concerns and the need for further research to safeguard their natural habitats.
