When I first got my Juwel 100 at age 12 (12 years ago) and started stocking it with fish, I bought a Corydoras Albino... and wow! What a fantastic fish this is. It's sociable, easy to keep, and a true community fish.
My name is Indy de Jong, and I've been keeping fish for 12 years. I share my knowledge online, and today I wrote a blog post about Corydoras. Enjoy reading!

What are the specific characteristics of Corydoras?
Corydoras, also known as armored catfish, are popular bottom-dwelling fish in the aquarium world. Let's take a look at what makes them so special:
1. Unusual appearance : With their rounded heads and large, expressive eyes, Corydoras resemble small underwater creatures, curiously exploring the world around them. Their striking black spots or stripes and excellent eyesight help them navigate the aquarium substrate and find food.
2. Numerous Species : Corydoras is a diverse genus with over 170 officially described species, meaning there's sure to be a variety to suit your aquarium.
3. Powerful : A Corydoras is a truly hardy fish! It's easy to keep and doesn't require much in the aquarium. Provide a good gravel substrate that they can siphon off (make sure it's not sharp). And provide a large enough tank with other Corydoras, and they'll thrive!
4. Tropical Origin and Temperature : They do best in an aquarium with a water temperature between 22 and 26 degrees Celsius, as they are native to South American tropical freshwater habitats.
5. Small Size and Social Behavior : With an average length of 5 to 10 centimeters, they are suitable for both large and small aquariums, and they thrive in groups of at least six individuals of the same species.
In short, the specific characteristics of Corydoras make them a valuable and fascinating addition to any aquarium.
How do Corydoras behave in an aquarium?
Corydoras are not only charming bottom-dwelling fish, but also fascinating creatures to observe in an aquarium. Their behavior and interactions add a vibrant dynamic to any aquatic environment. Let's take a look at how Corydoras behave in an aquarium and what this means for aquarium enthusiasts.
1. Social Behavior: Corydoras are naturally social fish and thrive in groups of at least six individuals. In a group, they exhibit interesting behaviors, such as swimming together throughout the tank and communicating with each other through subtle body language.
2. Swimming behavior: Despite being bottom-dwelling, Corydoras are quite active and enjoy swimming around in all parts of the aquarium. They not only explore the bottom in search of food, but also swim freely through the water, often in schools.
3. Feeding Behavior: Corydoras are omnivores and will be omnivorous in an aquarium. They constantly search for food on the bottom, where they feed on scraps, algae, and small organisms. It's a true delight to watch them dig and root around as they gather their meal.
4. Interaction with other fish: Corydoras are known for their peaceful nature and are generally compatible with a wide range of other fish. They are not likely to show aggression and are more likely to flee than fight in conflict situations.
5. Resting Behavior: Although Corydoras are quite active during the day, they are more at ease at night. They may retreat to hiding places or rest quietly on the aquarium floor during the night.
6. Communication: Corydoras use various forms of communication to interact with each other and mark their territory. This includes flashing their fins, body movements, and even vocalizations that can sometimes be heard.
The behavior of Corydoras in an aquarium is a source of joy and wonder for aquarists of all levels. By housing and observing them in a suitable environment, we can develop a deeper understanding of these charming bottom-dwelling fish and their unique behaviors.

What does a Corydoras armored catfish eat?
Corydoras aren't too picky when it comes to food. Here are some options you can consider for feeding these bottom-dwelling fish:
| Nutritional options | Description |
|---|---|
|
Special bottom food |
Soil tablets or pellets that disintegrate quickly and are easily consumed by Corydoras while rooting on the bottom. |
|
Frozen or live food |
Feed occasionally with frozen or live foods such as black mosquito larvae, artemia or tubifex to provide an additional protein source and encourage natural foraging behaviour. |
|
Regular flake food |
Small amounts of flake food that sinks to the bottom, offered as a supplement to the main diet. Make sure the food is small enough for Corydoras to easily consume. |
|
Green fodder |
Occasionally offer greens such as cooked peas, cucumber or zucchini to provide Corydoras with fiber and essential nutrients. |
|
Diet of algae and detritus |
Natural food such as algae and detritus (organic waste) that grows on the aquarium substrate. Ensure the aquarium is well maintained and that there is plenty of natural food available for Corydoras to graze on. |
These different food options can help provide a balanced diet for Corydoras, keeping them healthy and active in your aquarium. Experiment with different foods and observe how your Corydoras react to them to determine what works best for your fish.
