Sterbai Corydoras Care: Species Summary
Sterbai Corydoras (Corydoras sterbai) is a freshwater fish species native to South America.
These small, peaceful fish are a popular choice for aquarium enthusiasts due to their distinctive appearance and ease of care.
In this section, we will cover the essential information you need to know about Sterbai Corydoras care.
Origin
Sterbai Corydoras are native to the upper Paraguay River basin in Brazil. They can also be found in parts of Argentina and Bolivia.
These fish prefer slow-moving, shallow waters with sandy or muddy substrate.
Lifespan
The average lifespan of Sterbai Corydoras is around 5 years, but they can live up to 8 years in optimal conditions.
Appearance
Sterbai Corydoras have a distinctive appearance with their bronze body covered in black spots.
They also have two rows of bony plates on their sides, which provide protection against predators. These fish have a short, rounded snout and a pair of barbels on their mouth.
Size and Growth Rate
Sterbai Corydoras typically grow to be around 2.5 inches in length.
They have a slow growth rate and can take up to 2 years to reach their full size.
Behavior & Temperament
Sterbai Corydoras are peaceful and social fish that do best when kept in groups of at least 6 individuals.
They are active during the day and spend most of their time scavenging for food on the bottom of the tank.
These fish are not aggressive and can be kept with other peaceful community fish.
Male vs Female
It can be challenging to tell male and female Sterbai Corydoras apart.
However, females tend to be larger and rounder than males, especially when they are carrying eggs.
Tank Setup
Tank Size
When it comes to tank size for Sterbai Corydoras, bigger is always better. These fish are active swimmers and need plenty of space to move around.
A minimum tank size of 20 gallons is recommended for a small group of 4-6 fish.
However, if you have the space and resources, a larger tank of 40 gallons or more will provide even more room for these active fish to explore.
Lighting
Sterbai Corydoras do not have any specific lighting requirements.
However, it is important to provide a consistent day/night cycle to promote healthy behavior and natural rhythms.
A timer can be used to ensure a consistent lighting schedule.
Filtration & Aeration
A high-quality filter is essential for maintaining water quality in a Sterbai Corydoras tank.
A canister filter or hang-on-back filter is recommended, with a turnover rate of at least 5-6 times the tank volume per hour.
In addition to filtration, aeration is also important to provide oxygenation and prevent stagnant areas in the tank.
Heater
Sterbai Corydoras are tropical fish and require a consistent water temperature of 75-80°F.
A submersible heater can be used to maintain a stable temperature in the tank.

A fine-grained substrate, such as sand or small gravel, is recommended for Sterbai Corydoras.
This will allow them to sift through the substrate in search of food without injuring their sensitive barbels.
Decoration
Sterbai Corydoras appreciate plenty of hiding places and cover in their tank. Driftwood, rocks, and caves can all be used to create hiding spots for these fish.
However, it is important to avoid sharp or jagged decorations that could injure the fish.
Plants
Live plants can provide additional cover and hiding places for Sterbai Corydoras, as well as helping to maintain water quality.
Hardy, low-light plants such as Java Fern and Anubias are good choices for a Sterbai Corydoras tank.
Overall, a well-planned and maintained tank setup is essential for the health and happiness of your Sterbai Corydoras.
By providing plenty of space, hiding places, and clean water, you can create an ideal environment for these fascinating fish to thrive.
Personally, I have found that adding a few small pieces of driftwood to my Sterbai Corydoras tank has made a big difference in their behavior. They love to explore the nooks and crannies of the wood, and it has provided some great photo opportunities!
Water Quality
Water Temperature
Maintaining the right water temperature is crucial for the health and well-being of your Sterbai Corydoras.
These fish are native to the Amazon basin, where the water temperature is typically around 75-80°F.
Therefore, it is recommended to keep the water temperature in your tank between 75-80°F. Use a reliable aquarium heater to maintain the temperature within this range.
Avoid sudden temperature changes, as this can cause stress and even death in your fish.
Water pH
Sterbai Corydoras prefer slightly acidic water with a pH range of 6.0-7.5. It is important to monitor the pH level regularly using a reliable aquarium test kit.
If the pH level is too high or too low, it can cause stress and harm to your fish. You can adjust the pH level by adding pH-lowering or pH-raising products to your tank.
However, it is important to do this gradually and not make sudden changes that can shock your fish.
Water Hardness
These fish prefer soft to moderately hard water with a hardness level of 2-12 dGH. You can test the hardness level using a reliable aquarium test kit.
If the water is too hard, you can add peat moss or driftwood to the tank to soften it. If the water is too soft, you can add aquarium salt or minerals to increase the hardness level.
Water Changes
Regular water changes are important for maintaining good water quality in your tank. It is recommended to change 25% of the water in your tank every two weeks.
This will help remove any accumulated waste and toxins from the water. Use a gravel vacuum to remove any debris from the substrate during water changes.
Make sure to treat the new water with a water conditioner before adding it to the tank. I have found that maintaining good water quality is essential for the health and well-being of my Sterbai Corydoras.
By keeping the water temperature, pH, and hardness levels within the recommended range, and performing regular water changes, I have been able to keep my fish healthy and happy.
Tank Maintenance
Keeping your sterbai corydoras healthy and happy requires proper tank maintenance. This means regular cleaning and monitoring of water quality.
I personally recommend doing a partial water change of 20-30% every week to keep the water clean and fresh. This helps to remove any excess waste and debris that can build up in the tank over time.
It’s also important to regularly test the water for pH, hardness, and temperature. Sterbai corydoras prefer a pH of 6.5-7.5 and a water temperature between 72-78°F.
If you notice any significant changes in these levels, it’s important to take action to correct them as soon as possible to avoid stress or illness in your fish.
In addition to monitoring water quality, it’s important to keep the tank itself clean. This means regularly cleaning the substrate and any decorations or plants in the tank.
I recommend using a gravel vacuum to clean the substrate and a soft-bristled brush to clean any decorations or plants.
Lastly, it’s important to regularly check the filter and replace any filter media as needed. This helps to ensure that the water is being properly filtered and that any harmful toxins or waste are being removed from the tank.
By following these simple tank maintenance tips, you can help ensure that your sterbai corydoras are happy and healthy for years to come.
Tank Mates
Compatible Fish Species
Sterbai Corydoras are generally peaceful fish and can be kept with a variety of other community fish. They are social creatures and should be kept in groups of at least 6 individuals.
Some good tank mates for Sterbai Corydoras include:
- Tetras
- Guppies
- Platies
- Mollies
- Angelfish
It is important to avoid keeping aggressive or fin-nipping fish with Sterbai Corydoras as they can be easily stressed.
Incompatible Fish Species
Avoid keeping Sterbai Corydoras with aggressive or territorial fish such as cichlids or larger predatory fish.
Also, avoid keeping them with fish that have a tendency to nip at fins such as barbs or some species of tetras.
How Many Sterbai Corydoras Can Be Kept Together?
Sterbai Corydoras are social fish and should be kept in groups of at least 6 individuals. However, the number of Sterbai Corydoras that can be kept together depends on the size of the tank.
As a general rule, you should have at least 20 gallons of water for every 6 Sterbai Corydoras. This will ensure that they have enough space to swim and explore without feeling cramped.
I personally keep my Sterbai Corydoras with a group of neon tetras and they all get along great. It’s fun to watch them swim and play together in the tank.
Just remember to keep the tank clean and well-maintained to ensure the health and happiness of your fish.
Diet
Corydoras Sterbai are omnivores, which means they require both plant-based and meat-based foods to maintain a healthy diet.
In the wild, they feed on insect larvae, small crustaceans, and plant matter.
In captivity, they can be fed a variety of foods to ensure they get all the necessary nutrients.
What To Feed
I feed my Sterbai Corydoras a combination of high-quality pellets, frozen or live foods, and fresh vegetables.
Pellets should make up the bulk of their diet, with frozen or live foods given as a treat a few times a week.
Some popular frozen or live foods for Corydoras include bloodworms, brine shrimp, and daphnia. Vegetables like zucchini, cucumber, and spinach can also be offered.
Frequency
I feed my Sterbai Corydoras twice a day, once in the morning and once in the evening.
It’s important not to overfeed them, as this can lead to health problems and poor water quality in the tank.
Only give them as much food as they can eat in a few minutes, and remove any uneaten food after feeding.
Tips
One important tip for feeding Sterbai Corydoras is to make sure the food sinks to the bottom of the tank. They are bottom-dwellers and won’t eat food that’s floating on the surface.
You can also try feeding them at night when the lights are off, as they are more active and likely to eat at this time. Finally, make sure to vary their diet to ensure they get all the necessary nutrients.
Common Diseases
Diseases
Sterbai Corydoras are generally hardy fish and are not prone to many diseases. However, like all fish, they can still fall ill if their tank conditions are not optimal.
The most common diseases that affect Sterbai Corydoras are bacterial infections, fungal infections, and parasitic infections.
Symptoms
Symptoms of bacterial infections in Sterbai Corydoras include fin rot, bloating, and lethargy.
Fungal infections can cause white patches on the skin, fins, and eyes.
Parasitic infections can cause the fish to scratch against objects in the tank, have difficulty breathing, and lose their appetite.
Treatment
If you notice any of these symptoms, it is important to take action quickly. Quarantine the affected fish and treat them with medication.
Antibiotics can be used to treat bacterial infections, while antifungal medication can be used to treat fungal infections.
Parasitic infections can be treated with medication such as copper sulfate or formalin.
Prevention
The best way to prevent diseases in Sterbai Corydoras is to maintain good water quality in the tank.
Regular water changes, proper filtration, and a clean substrate can go a long way in preventing diseases.
It is also important to avoid introducing new fish to the tank without quarantining them first. This can prevent the spread of diseases to your existing fish.
I once had a Sterbai Corydoras in my tank that began to show signs of bloating and lethargy. I quickly quarantined the fish and treated it with antibiotics.
Thankfully, the fish made a full recovery and was back to its active and playful self in no time.
It is important to keep a close eye on your fish and take action quickly if you notice any signs of illness.

Breeding
Breeding Setup
Breeding Sterbai Corydoras can be a fun and rewarding experience. To get started, you’ll need a breeding setup.
A breeding setup can be as simple as a 10-gallon tank with a sponge filter and a heater. Add some smooth rocks or spawning mops for the fish to lay their eggs on.
Keep the water temperature around 78°F and the pH between 6.5 and 7.0. Make sure the water is clean and well-aerated.
How To Breed
To breed Sterbai Corydoras, you’ll need a male and a female. The male will chase the female around the tank, and when he’s ready to spawn, he’ll wrap his body around hers and fertilize her eggs as she lays them.
The female will lay her eggs on a smooth surface, such as a rock or spawning mop.
After the eggs are laid, remove the adults from the breeding tank to prevent them from eating the eggs.
Care
After the eggs are laid, they will hatch in about 3-5 days. The fry will be very small and will need to be fed small amounts of food several times a day.
Baby brine shrimp or crushed flake food are good options. Keep the water clean and well-aerated, and make sure the temperature stays around 78°F.
As the fry grow, you can gradually increase the amount of food you feed them. Breeding Sterbai Corydoras can be a fun and rewarding experience.
It’s important to have a breeding setup that provides the right conditions for the fish to spawn, and to take good care of the eggs and fry once they hatch.
With a little patience and care, you can successfully breed these beautiful fish and watch them grow. I remember the first time I successfully bred Sterbai Corydoras.
It was such a thrill to watch the male wrap his body around the female and fertilize her eggs. Seeing the tiny fry hatch and grow was also very exciting.
Breeding fish is a great way to learn more about their behavior and biology, and it’s a lot of fun too!
