Species Overview

Corydoras semiaquilis, also known as the Peru Black Cory, belongs to the genus Corydoras and is part of the Callichthyidae family. This species is commonly referred to by various names such as Peru Black Cory, Panzerwels in Germany, and Sort Pansermalle in Denmark.

Origin & Distribution

These fish are native to the Western Amazon River basin, specifically found in the tributaries of the upper Rio Salimões in Amazonas, Brazil. They inhabit rivers and streams within their natural habitat. In terms of diet, Corydoras semiaquilis are omnivorous creatures that consume a variety of plant matter and small organisms.

Physical Characteristics

Corydoras semiaquilis can be recognized by their distinct physical features. They possess twin rows of armor plates along their flanks which provide them with protection. The specific epithet “semiaquilus” refers to the partial dark coloring on their upper body scutes, giving them a unique appearance.

Size, Growth Rate, & Lifespan

These fish typically reach a size of about 60mm (2.4 inches) in standard length (SL). They have a relatively slow growth rate that can vary depending on factors like tank conditions and feeding habits. When kept in suitable aquarium conditions, Corydoras species generally have a lifespan ranging from 5 to 10 years.

Habitat & Tank Conditions

Corydoras semiaquilus requires an adequately sized tank for their well-being. These peaceful creatures need the right environment in order to thrive.

Tank Size & Set Up

A tank size of at least 20 gallons is recommended to provide ample swimming space for these active little fish. It’s important to set up the tank with proper filtration to maintain good water quality.

Water Parameters

Maintaining suitable water conditions is crucial for the health of corydoras semiaquilus. These fish thrive in temperatures ranging from 72°F to 78°F (22°C to 26°C). The pH level should be kept between 6.5 and 7.5, while water hardness should ideally fall within the range of 2-12 dKH. Regular monitoring of these parameters is essential to ensure a stable environment for your fish.

Substrate & Decor

Creating a natural and comfortable environment for corydoras semiaquilus involves providing suitable substrate and decor in the tank. A sandy or fine-grained substrate is preferred, as it mimics their natural habitat and allows them to sift through it in search of food. Adding live plants, driftwood, and rocks can create hiding spots and mimic their native biotope.

It’s important to note that frequent water changes are necessary to maintain optimal water conditions and prevent any buildup of harmful substances. Corydoras semiaquilus are sensitive to poor water quality, so regular maintenance is key.

Remember that each species has its own specific requirements, so always do thorough research before adding any new fish species to your aquarium.

Opt for smooth gravel substrate to keep them from harm and encourage their natural burrowing behavior.

Tankmates & Temperament

These fish are known for their peaceful nature and ability to coexist with other non-aggressive species. They generally get along well with tankmates, making them a great addition to community aquariums.

Compatible Tank Mates

For those considering adding Corydoras Semiaquilus to their tank, it’s important to choose compatible tank mates that share similar water parameter preferences. Here are some suggested options:

Peaceful Community Fish: Species such as tetras, rasboras, guppies, and mollies can make good companions for Corydoras Semiaquilus. These fish have similar temperaments and will likely coexist harmoniously in the same tank.

Bottom-Dwelling Species: Since Corydoras Semiaquilus are bottom-dwellers themselves, they often do well when kept with other bottom-dwelling species like dwarf cichlids or loaches. This allows each species to occupy different areas of the tank without much competition.

Tank Mates to Avoid

While Corydoras Semiaquilus can peacefully coexist with many species, there are certain tank mates that should be avoided:

Larger or Aggressive Fish: It’s essential to avoid keeping Corydoras Semiaquilus with larger or aggressive fish that may intimidate or harm them. Predatory fish or those known for nipping fins should be kept separate from these peaceful catfish.

Territorial Fish: Some fish species can be territorial and may not tolerate the presence of other bottom-dwelling fish like Corydoras Semiaquilus. Examples include some types of cichlids or territorial bettas.

By carefully selecting compatible tank mates and avoiding aggressive or territorial species, you can ensure a harmonious community aquarium where your Corydoras Semiaquilus can thrive.

Corydoras semiaquilus Care

To ensure the well-being of your corydoras semiaquilus, there are a few important aspects of care to consider. Let’s delve into each one:

Care Recommendations

Maintaining good water quality is crucial for the health of your corydoras semiaquilus. Regular water changes and monitoring ammonia levels are essential. By performing routine water changes, you can remove any accumulated waste and toxins, keeping the aquarium environment clean and safe for your fish.

Diet & Nutrition

Proper feeding practices play a significant role in the overall health of corydoras semiaquilus. It’s important to provide them with a balanced and varied menu. Offer them high-quality sinking pellets or granules specifically formulated for bottom-dwelling fish like corydoras.

Supplement their diet with frozen or live foods such as bloodworms, brine shrimp, and daphnia to mimic their natural feeding habits. Feed them small portions multiple times a day to prevent overeating and ensure they receive adequate nutrition.

Breeding the Corydoras semiaquilus

To successfully breed the Corydoras semiaquilus, it’s important to understand their breeding behavior and create the right conditions in a separate breeding tank. These small catfish are known for their unique spawning habits and require specific care during the breeding process.

Recommended Tank Set Up

Creating the ideal environment is crucial for inducing spawning in Corydoras semiaquilus. Consider these factors when setting up your breeding tank:

Temperature fluctuations: Mimic natural conditions by providing slight temperature variations, as this can stimulate spawning.

Increased oxygenation levels: Ensure proper filtration and aeration to maintain high oxygen levels, which are essential for successful breeding.

Breeding Process

Follow these tips to encourage successful breeding of Corydoras semiaquilus:

  1. Separate breeding tank setup: Create a dedicated tank with suitable substrate (such as fine sand) and hiding places like caves or plants. This gives the fish a comfortable space for spawning.
  2. Introduce compatible pairs: Place one male and one female into the breeding tank. It’s important to ensure that they are mature and healthy individuals.
  3. Provide optimal conditions: Maintain water parameters within acceptable ranges, including temperature, pH, and hardness specific to this species. Regular water changes are also necessary.

Fry Care

Once spawning occurs, it’s essential to provide proper care for the fry (baby fish):

Remove adults from the tank: After eggs have been laid, transfer both parents back to their original aquarium to protect them from potentially eating their own eggs or fry.

Protecting eggs and fry: Ensure that there is sufficient cover (like moss or mesh) in the tank to prevent other fish from preying on the eggs or fry.

Feed specialized food: Offer newly hatched brine shrimp or commercially available fry food specifically designed for small catfish.

Breeding Corydoras semiaquilus can be a rewarding experience for aquarists. By understanding their breeding behavior and providing the right conditions, you can increase the chances of successful spawning and raise healthy fry.
