Amanda Jane Corydoras - Corydoras amandajanea : Complete Fish Profile & Care Guide
Table of contents
Introduction
A rarely imported, larger-growing species of Corydoras, Amanda Jane Corydoras (Corydoras amandajanea) are peaceful, hardy, and active. This species makes a striking addition to a community or planted aquarium and are suitable for both novice and experienced aquarists alike.
Keeping Amanda Jane Corydoras in a group of at least six individuals is recommended to ensure they thrive and display their natural behaviours. These Corys are great community fish and can be housed with other temperate species such as Tetras, Pencilfish, Dwarf Cichlids and smaller Barbs. However, it is crucial to avoid housing them with aggressive fish that may harm them.
To create a suitable habitat for Amanda Jane Corydoras, a mature aquarium with fine sand or smooth gravel is ideal. Adding driftwood branches, aquatic plants and dried leaf litter will provide these fish with a secure environment and mimic their natural habitat. Regular water changes are also necessary to ensure their well-being.
Amanda Jane Corydoras exhibits a notable degree of variability in its colour pattern. The light-coloured body typically showcases only a sparse number of markings, including a dark eye band and a rectangular blotch positioned just below the dorsal fin. Additionally, a distinct bright and shining marking in the neck region aids in identifying and recognizing conspecifics.
Notably, the body may display fine spotting or present a plain appearance, with certain individuals featuring relatively larger dark spots on their bodies. When illuminated from a lateral angle within the tank, the flanks can reveal a captivating and vibrant bright green shine.

Natural Habitat
Amanda Jane Corydoras are exclusively native to the upper and middle Rio Negro Basin, located in Brazil, South America. These Corydoras thrive in habitats characterized by soft, acidic, and shallow waters with a fine sandy substrate, where they are frequently encountered in significant aggregations as they engage in foraging activities.
Breeding
The process of breeding Amanda Jane Corydoras can be facilitated with relative ease by ensuring the provision of proper water parameters within a dedicated breeding tank. A successful breeding endeavour is often enhanced by having a ratio of two males for every female and providing an abundance of aquatic plants that offer suitable surfaces for the females to deposit their eggs.
To stimulate spawning, a reduction in water temperature, along with increased oxygenation and water flow, is recommended. This adjustment should be implemented on a daily basis until spawning is observed. Following the completion of the spawning process, it is advisable to promptly remove either the eggs or the adult fish from the breeding tank. If transferring the eggs, meticulous attention should be given to maintaining consistent water conditions and ensuring ample oxygen supply.
Typically, the eggs hatch within three to four days, and the resulting fry can be nourished with live foods such as microworms and baby brine shrimp. Sustaining a healthy environment for the fry is paramount to safeguard against potential diseases, especially during their initial developmental months. Diligent care and attention during this critical period will significantly contribute to the well-being and long-term success of the young Corydoras.
Diet & Feeding
Amanda Jane Corydoras exhibit a non-discriminatory palate and readily relishes a diverse assortment of foods, including frozen, live, and freeze-dried varieties. As bottom-dwelling fish, they particularly benefit from sinking pellets and algae wafers, which are highly recommended for their diet.
To further ensure well-balanced nutrition, incorporating vegetables such as cucumber, spinach, and peas can be advantageous.
Maintaining a clean tank environment is essential, and promptly removing any uneaten food is crucial to prevent the accumulation of waste.
However, it is essential to avoid any expectation that these Corydoras can thrive solely on "leftovers" from other aquarium inhabitants or be relied upon to serve as "cleaners" for the aquarium. To ensure their well-being and health, a balanced and purposeful feeding regimen should be consistently provided.
