Description

Species Background
Black Schultzei Corydoras (Corydoras schultzei) is a small armored catfish from South America associated with tributaries of the Amazon basin in Brazil. Like other members of the Callichthyidae family, it inhabits slow-moving creeks, shallow floodplains, and forest streams where soft sediments, leaf litter, and submerged wood dominate the bottom. These environments provide constant micro-invertebrate food sources and calm water conditions ideal for bottom-foraging fish.

The species is recognized for its darker body coloration compared to many other Corydoras and retains the classic armored plates and sensitive barbels used to sift through sand and detritus while feeding.

Behavior and Temperament
Black Schultzei Corydoras are peaceful bottom dwellers that spend most of their time searching the substrate for food. They are social fish and display their most natural behavior when kept in groups.

They coexist well with other calm community fish including small tetras, rasboras, dwarf cichlids, and peaceful livebearers. When kept in proper groups they become more active, frequently moving together across the substrate while foraging.

Adult Size
Adults typically reach about 2.5–3 inches in length.

Water Parameters
Temperature: 72–79°F
pH: 6.0–7.8
GH: 2–15 dGH
KH: 1–8 dKH

As with most Corydoras species, stable and clean water conditions are more important than chasing exact numerical targets.

Diet
Black Schultzei Corydoras are omnivorous bottom feeders that naturally consume small invertebrates, insect larvae, and organic material found in the substrate.

In aquariums they readily accept sinking pellets, quality bottom-feeder wafers, frozen foods such as bloodworms or brine shrimp, and occasional live foods. A varied diet helps maintain strong health and natural behavior.

Tank Requirements
A tank of at least 20 gallons is recommended for a small group. Corydoras should always be kept in groups of five or more individuals.

A soft sand or smooth fine substrate is strongly recommended because these fish constantly sift through the bottom with their barbels. Sharp gravel can damage these sensory organs over time.

Provide open areas for foraging along with driftwood, plants, and shaded areas. Moderate filtration and good oxygenation help replicate the conditions found in their natural habitat.

Why They’re Popular
These fish are popular because they combine the classic Corydoras personality with a darker, distinctive appearance. Aquarists enjoy them for their constant activity, peaceful nature, and usefulness as bottom-level community fish.

In well-established aquariums they spend the day cruising the substrate together, constantly searching for food while adding movement and personality to the lower levels of the tank.
