The water temperature should be slightly higher than usual and regular water changes are necessary to simulate the rainy season in their natural habitat. The eggs will hatch in about a week, and the fry will require small live or frozen foods to survive.

Caring for Corydoras ambiacus in an aquarium requires providing them with a suitable environment that mimics their natural habitat. This includes providing them with a soft sandy substrate, ample hiding places such as caves or driftwood, and at least a 30-gallon tank for a small group of these fish. It is important to maintain good water quality by regularly monitoring and adjusting the temperature, pH level, and performing routine water changes.

Diet and feeding habits of Corydoras ambiacus

The diet and feeding habits of Corydoras ambiacus play a crucial role in maintaining their health and overall well-being. These small freshwater catfish have specific dietary requirements that need to be met for them to thrive in aquarium environments.

1. Diet: Corydoras ambiacus are primarily omnivores and have a diverse diet. They feed on a variety of food sources such as live, frozen, and dry foods. It is important to provide them with a balanced diet to ensure their nutritional needs are met. A combination of high-quality pellets, flakes, and granules specifically formulated for catfish should be the staple part of their diet.

2. Feeding Habits: Corydoras ambiacus are bottom-dwelling fishes, and their feeding habits reflect this behavior. They have specialized mouths that allow them to forage and sift through the substrate in search of food particles. They use their barbels, which are sensory organs, to detect food and explore their surroundings.

When feeding Corydoras ambiacus, it is important to take their natural feeding behavior into consideration. Avoid overfeeding as it can lead to serious health problems and water quality issues in the aquarium. Feed them in small portions 2-3 times a day, making sure they consume all the food within a few minutes. Uneaten food should be promptly removed to maintain water quality.

List of suitable foods:

Live/Frozen Foods Dry Foods
Brine shrimp Catfish pellets
Daphnia Catfish flakes
Bloodworms Algae wafers
Tubifex worms Spirulina pellets

While live and frozen foods provide a more varied and natural diet, dry foods can serve as a convenient option to supplement their nutrition. It is important to offer a mixture of both to ensure a well-balanced diet for your Corydoras ambiacus.

Breeding behavior of Corydoras ambiacus

Corydoras ambiacus, also known as the dwarf cory, is a popular freshwater fish among aquarium enthusiasts. One of the fascinating aspects of these fish is their interesting breeding behavior. It is a delightful experience to witness the courtship and spawning rituals of these tiny creatures. Let’s delve into the intricate details of how Corydoras ambiacus breeds, and explore the key factors that contribute to their successful reproduction.

1. Courtship rituals:

When it comes to breeding, Corydoras ambiacus engages in elaborate courtship rituals. The males actively pursue the females, fluttering their fins and shaking their bodies in a mesmerizing display. The females, on the other hand, respond by swimming seductively and displaying their receptive behavior. These courtship rituals are not only visually captivating, but they also play a vital role in the selection of mates.

2. Spawning process:

Once a suitable mate is chosen, the pair embarks on the spawning process. Corydoras ambiacus is an egg-laying species, and the female typically lays a batch of eggs on a flat surface, such as leaves or rocks, in the aquarium. The male simultaneously releases his milt to fertilize the eggs. This synchronized act ensures the successful fertilization of the eggs, increasing the chances of viable offspring.

3. Care for the eggs and fry:

After the eggs are fertilized, both the male and female play an active role in caring for their offspring. They diligently guard the eggs, ensuring their safety and providing them with oxygenation by fanning them with their pectoral fins. In about 4-7 days, depending on water conditions, the eggs hatch, and the fry emerge. At this stage, it is recommended to provide the fry with appropriate size and nutritious food, such as freshly hatched brine shrimp or specialized fry food, to support their growth and development.


The breeding behavior of Corydoras ambiacus demonstrates their intricate reproductive strategies and their commitment to ensuring the survival of their offspring. Watching these fish engage in courtship rituals and witnessing their dedication towards their eggs and fry is truly a captivating experience. By understanding the breeding behavior of Corydoras ambiacus, aquarium enthusiasts can create an environment conducive to successful reproduction and contribute to the preservation of this beautiful species in captivity.
