General Description
Brachyrhamdia Meesi, a member of the Heptapteridae family, is rare in the aquarium trade and usually arrives as bycatch in shipments of other fish. Easily distinguished by the dark vertical bar through the eye, it mimics other species such as Otocinclus and Corydoras during different life stages. This catfish has longer barbels and lacks body scute-like plates, setting it apart from Corydoras. Molecular studies suggest its closest relations are with Pimelodidae, Pseudopimelodidae, and Conorhynchos.
Aquarium Setup
For Brachyrhamdia Meesi, a tank with fine sand substrate, driftwood, and branches is recommended. While not common in its natural habitat, plants like Microsorum, Taxiphyllum, Cryptocoryne, and Anubias can be added. The species necessitates pristine water conditions and is intolerant of organic waste accumulation, requiring regular partial water changes to ensure optimal health.
Behaviour
Generally non-aggressive, Brachyrhamdia Meesi may consume very small fish and is not suited to cohabitate with Corydoras due to reasons discussed in notes. While not highly social with its kind, keeping multiple individuals is possible in a suitably sized aquarium.
Feeding and Diet
In nature, Brachyrhamdia Meesi predominantly preys on benthic invertebrates. In captivity, a diet of live and frozen foods like Artemia, Daphnia, and bloodworms is recommended. Additionally, sinking dried foods are accepted by this species.
Reproduction & Dimorphism
The reproductive habits of Brachyrhamdia Meesi are largely undocumented. However, studies on B. imitator show spawning being initiated by a group of cohabiting Corydoras, followed by the Brachyrhamdia's spawning. Mature females can be distinguished by their fuller body compared to males.
Habitat and Distribution
The species originates from near Belem, Brazil, specifically in the Pará state near the mouth of the Amazon River. Its exact distribution is unclear, with reports also placing it in the Río Madre de Dios basin in southeastern Peru, thousands of kilometers away from its type locality.
