This tropical freshwater fish, also known as the false corydoras (Aspidoras pauciradiatus), is a member of the Corydoradinae sub-family under the Callichthyidae family. The upper Araguaia River basin in Brazil is where it was first discovered, in South American interior waters.

Sixray corydoras are commonly referred to as False Corydoras. Sixray corydoras are bottom feeders, so they spend much of their time foraging for morsels on the substrate looking for dead or dying plant material, algae, and other food quickly breaking down. They will generally cling to the surface with their barbels to secure themselves in place while scraping up bits of food left behind by larger fish.

This post will cover the breeding requirements and habitat needs for sixray corydora fish as well as some tips on feeding them.

Sixray Corydoras Diet

Sixray corydoras are mostly scavengers, but will also take live worms and feed off of algae mats. Feeding them dry foods is not recommended as they do not enjoy the hard texture. They also need their water to be well-oxygenated so it may be necessary to move them to a larger tank if they are living in a small aquarium. They should be fed at night since they are nocturnal.

Aspidoras Pauciradiatus Breeding 

These Sixray corydoras are not a commonly available type of fish. Sixray corydoras require specific water conditions to successfully breed, so these fish can only be purchased from specialty retailers or online.

Sixray Corydoras Upkeeping

Sixray corydoras need clean and well maintained water to properly breed. This means that in the months leading up to spawning, hard water is best for the spawning process. Most importantly, Sixray corydoras need a source of oxygen for breeding purposes.The breeding process for It is quite difficult to breed Aspidoras pauciradiatus – Sixray corydoras. The water should be acidic (pH 6) and soft (GH 0-1). The eggs are placed and fertilized amongst fine-leaved plants when the water is changed by 75%. It is best to shift the eggs to another tank after they have hatched. When the newborn fish are able to swim freely, they can be raised on vinegar-eels and, a few days later, with baby brine shrimp. Sixray corydoras usually begins once the temperature starts warming at least 79°F (26°C).

Aspidoras Pauciradiatus Caution

In order to protect the barbels of this species avoid sharp gravel, it is best to keep it in a tank with sand or round pebbles.

When handling Aspidoras pauciradiatus since it has hardened pectoral spines that may puncture human flesh, a plastic container should be used and a net should not be utilized because these spines may get entangled in the mesh.

Sixray corydoras are indeed venomous. It is hypothesized that axillary glands with slightly poisonous secretions exist near the base of each spine.

Because these fish lack scales, they are particularly salt-sensitive, and adding salt to the aquarium can harm them.
