Discover everything you need to know about the characteristics of Sterba’s Corydoras in this comprehensive guide. A must-read for fish enthusiasts!
Introduction to Sterba’s Corydoras
Sterba’s Corydoras, also known as Corydoras sterbai, are a species of small armored catfish that are native to South America, specifically found in tributaries in Bolivia and Brazil. They are a striking species with white spots on a dark brown base on the face, which extends into the fins, and orange-tinted pectoral fins in mature individuals.
Corydoras sterbai are best suited for aquariums ranging from 20-30 gallons in size, and they strongly prefer to be kept in schools of 3-6 individuals. Their ideal enclosure should feature a fine sandy substrate for them to root around in for food, as larger gravel may injure their sensitive mouthparts. Additionally, they prefer slightly higher than average temperatures, with an acceptable range of 75-82 degrees Fahrenheit, and a pH range of 6.0-7.6.
Compatibility and Breeding
Corydoras catfish are known for being highly compatible with many different types of community fish, and they should be housed with their own kind or similar species of Corydoras. When triggered to spawn, they are among the easiest of the cory cats to breed, with the best ratio for breeding being 2-3 males for every female. The eggs are tough and can be manually removed for incubation, and the fry can be fed microworms or live baby brine shrimp.

Behavioral traits of Sterba’s Corydoras
Sterba’s corydoras are peaceful and social fish that prefer to be kept in groups of their own kind or with similar species. They are active bottom-dwellers and spend much of their time foraging for food in the substrate. These catfish are known for their playful behavior, often seen darting around the aquarium and interacting with each other. They are also known to be quite curious and may investigate new additions to the tank.
Social Behavior
In their natural habitat, Sterba’s corydoras are found in large groups, and they display this same social behavior in the aquarium. They are most active and comfortable when kept in groups of at least 3-6 individuals. When housed in smaller numbers, they may become stressed and exhibit shy or reclusive behavior. In a well-established and properly maintained aquarium, these catfish will often swim and feed together, showcasing their social nature.
Foraging and Feeding
Sterba’s corydoras are efficient scavengers and spend much of their time sifting through the substrate in search of food. They have specialized barbels around their mouths that help them locate and consume food particles. In the aquarium, they will eagerly accept a variety of sinking foods, including pellets, wafers, and live or frozen foods. Observing them forage and feed can be quite entertaining, as they are constantly on the move and interact with the environment in search of sustenance.
Habitat and environment requirements for Sterba’s Corydoras
Sterba’s Corydoras are native to tributaries in Bolivia and Brazil, so it is important to replicate their natural habitat in the aquarium. They prefer a well-planted tank with plenty of hiding spots, such as driftwood, rocks, and caves. Live plants like Java fern, Amazon sword, and Anubias are great additions to the aquarium as they provide cover and help maintain water quality.
Substrate
Sterba’s Corydoras prefer a fine sandy substrate in the aquarium. This allows them to root around for food without injuring their sensitive barbels. It is important to avoid using larger gravel, as it may harm the catfish’s mouthparts.
Water parameters
These catfish thrive in slightly higher than average temperatures, with an acceptable range of 75-82 degrees Fahrenheit. They also prefer neutral to slightly acidic water, with an ideal pH range of 6.0-7.6. It is recommended to use leaf litter or blackwater extract to naturally lower the pH in the aquarium. Regular water changes and maintenance are essential to ensure the water parameters remain within the suitable range for Sterba’s Corydoras.
Breeding and caring for Sterba’s Corydoras
Breeding Sterba’s Corydoras
Sterba’s cory catfish are relatively easy to breed in a home aquarium. To trigger spawning, a cool water change can be performed. A ratio of 2-3 males for every female is recommended for breeding. The males will chase the female and form a “T-position” by grasping her barbels with their pectoral fins. The female will lay a few eggs at a time, typically on the glass of the aquarium or the underside of plants. The eggs can be manually removed and incubated with methylene blue in a small aquarium or container with an air stone or sponge filter. The eggs will hatch in 3-5 days, and the fry can be fed microworms or live baby brine shrimp once they absorb their yolk sac.
Caring for Sterba’s Corydoras
Sterba’s cory catfish are best kept in groups of 3-6 individuals in an aquarium of at least 20-30 gallons. They prefer a fine sandy substrate to root around in for food, as larger gravel may injure their sensitive mouthparts. These catfish also prefer slightly higher than average temperatures, with an acceptable range of 75-82 degrees Fahrenheit. Regular water changes of 25-50% and monthly filter maintenance are essential for maintaining their ideal environment. They are omnivorous scavengers and should be offered a complete diet, such as gel diets, sinking wafers, and frozen offerings. Additionally, they are known for being highly compatible with many different types of community fish and should be housed with tropical species.
In conclusion, Sterba’s Corydoras is a peaceful, social, and hardy fish species that is ideal for community aquariums. With its distinct appearance and easy care requirements, it makes a great addition to any freshwater tank.
