General Description
Trachelyichthys Decaradiatus, very similar to T. exilis, can be distinguished by its forward-set eye and broader, shorter humeral process. It belongs to the Auchenipteridae family and is typically around 8.0cm in size. This species is not commonly found in the aquarium trade and is known only from the Rupununi River in Guyana.
Aquarium Setup
Ideally, Trachelyichthys Decaradiatus thrives in a heavily planted aquarium with subdued lighting. Floating plants can help diffuse the light, as these fish do not appreciate bright conditions. Providing open swimming spaces amidst the vegetation is recommended for their well-being. Water parameters should be maintained at a pH of 6.5-7.0, hardness of 8-15°dH, and a temperature range of 20-28°C (see table for detailed tank setup).
Behaviour
This species is peaceful towards most tankmates and is safe in community setups. It shows no aggression towards its own kind and prefers being in a group. Keeping them with tetras, dwarf cichlids, and peaceful catfish like Corydoras species in a South American biotope tank is ideal for their social behavior.
Feeding and Diet
Trachelyichthys Decaradiatus prefers live and frozen foods such as bloodworms, earthworms, and prawns but can also be fed small pellets or flakes. Unlike many of its relatives, it will actively feed during daylight hours, making it easier to observe and maintain in an aquarium setting.
Reproduction & Dimorphism
There is no reported information on the reproduction of Trachelyichthys Decaradiatus in aquarium conditions. Males possess a heavily modified anal fin, similar to livebearers' gonopodium, while females appear rounder when gravid, showing sexual dimorphism in body shape.
Habitat and Distribution
Inhabiting the Rupununi River and its tributaries in Guyana, Trachelyichthys Decaradiatus is typically found in river environments. Its natural habitat comprises areas with dense vegetation and a mix of open swimming spaces, replicating this in the aquarium setup can enhance the well-being of these fish.
