Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

Corydoras amapaensis are peaceful, social schooling fish that thrive when kept in groups. Keeping them in numbers of at least six individuals greatly reduces their stress and promotes natural behaviors. They are completely harmless to plants and other tank inhabitants.

Diet

Omnivore

These are omnivorous bottom feeders that require a varied diet to thrive. Their meals should include high-quality sinking pellets, wafers, and live or frozen foods like bloodworms. A balanced diet ensures proper growth and vibrant coloration for Corydoras amapaensis.

Sex ratio

Specific M:F ratio

Maintaining a ratio of two or three males for every female is ideal for breeding purposes. This ratio encourages natural spawning behaviors and increases the chances of successful fertilization. In non-breeding community tanks, the exact ratio for Corydoras amapaensis is less critical.

Feeding frequency

Twice daily

They should be fed small amounts once or twice a day. It is important to provide only what Corydoras amapaensis can consume within a few minutes to prevent water fouling. Occasional fasting days can also be beneficial for their digestive health.

Bioload

The Corydoras amapaensis has a relatively low bioload compared to many other species of similar size. They are efficient scavengers that help keep the substrate clean, which slightly offsets their waste production. However, adequate biological and mechanical filtration is still necessary to maintain optimal water quality in the aquarium.

Flow

Stagnant

They prefer moderate water movement that simulates their natural riverine habitats. A gentle current provides necessary oxygenation without exhausting the fish. Avoid overly strong flow that could sweep Corydoras amapaensis away or cause stress.

Reproduction

Oviparous

Breeding Corydoras amapaensis in captivity is possible but requires specific water conditions and conditioning. They are egg layers that typically deposit their adhesive eggs on broad leaves or the aquarium glass. Parents may eat the eggs, so it is often best to raise the fry in a separate tank.

Compatibility & tankmates

They are incredibly peaceful and make excellent additions to community aquariums. Corydoras amapaensis gets along well with most other peaceful, similarly sized fish. Aggressive or large tank mates should be avoided as they may intimidate or harm them.

Tank level

Bottom

They are obligate bottom dwellers that spend the majority of their time on the substrate. Corydoras amapaensis constantly rummage through sand or smooth gravel in search of food. Very rarely will they be seen swimming in the middle or upper levels of the water column.
