  • These fish typically reach around 2.8 inches in size and can live for five to ten years with proper care.

Species Overview

Corydoras geoffroy, also known as Geoffroy’s Cory or Ulvepansermalle (Denmark), belongs to the Corydoradinae subfamily. These small freshwater fish are commonly found in coastal rivers of Suriname and French Guiana, including Guyana Waters, Coastal Rivers of Guyanas, and Marowijne.

Corydoras geoffroy is easily identified by its twin rows of armor plates along the flanks and fewer than 10 dorsal fin rays. These unique features make them stand out among other species.

One fascinating characteristic of Corydoras geoffroy is their ability to breathe air. They are facultative air breathers, meaning they can take in oxygen from the atmosphere. Their tiltable eyes allow them to gulp air when needed. These fish possess axillary glands at the base of each spine that are believed to contain mildly toxic secretions.

In terms of size, Corydoras geoffroy typically reaches around 70mm or 2.8 inches SL. They have a relatively slow growth rate but reach maturity within their first year of life. With proper care, these fish can live for five to ten years or even longer.

These species primarily feed on small organisms such as insects and crustaceans found in their natural habitat. They may also consume plant matter and benefit from dense vegetation for hiding and spawning purposes.

Habitat & Tank Conditions

To recreate the natural habitat of Corydoras geoffroy, it is important to consider the tank size, substrate, vegetation, and water parameters.

Tank Size & Set Up

Corydoras geoffroy requires a suitable tank size to thrive. It is recommended to provide a tank with a minimum size of 20 to 30 gallons (75 to 115 liters) for a group of six or more individuals. Maintaining good water quality through proper filtration and regular maintenance is crucial for their well-being.

Need for a Tank Cover

Due to their ability to breathe atmospheric air, it is essential to have a tank cover for Corydoras geoffroy. This prevents them from jumping out of the aquarium and ensures their safety.

Water Parameters

Corydoras geoffroy prefers specific water parameters in captivity. They thrive in a pH range of 6.0 to 8.0 and can tolerate a dH range of 2 to 25. The temperature range for their habitat should be maintained between 22°C to 26°C.

Substrate & Decor

Recreating their natural environment involves providing suitable substrate and decor options. Corydoras geoffroy prefers sand as the substrate in the aquarium. They require shade provided by overhanging rock work, arching bogwood, tall or floating plants as hiding places.

By carefully considering these factors when setting up an aquarium for Corydoras geoffroy, you can create an environment that closely resembles their natural habitat. This will contribute to their overall health and well-being in captivity.

Tankmates & Temperament

Corydoras geoffroy, also known as Geoffroy’s catfish, are peaceful and non-aggressive fish that can coexist harmoniously with other species in the aquarium. These sociable creatures thrive when kept in groups of at least six individuals of the same species.There are a few things to consider to ensure a compatible and stress-free environment for your Corydoras geoffroy.

Behavior

The peaceful nature of Corydoras geoffroy makes them an excellent addition to community tanks. They generally get along well with most other peaceful fish types, making them highly compatible tankmates. Their calm demeanor and non-aggressive behavior contribute to a tranquil atmosphere within the aquarium.

Compatible Tank Mates

When selecting tankmates for Corydoras geoffroy, it is crucial to choose species that share similar temperament and environmental requirements. Here are some suggestions for compatible tankmates:

  • Tetras (such as Neon tetras or Cardinal tetras)
  • Rasboras (such as Harlequin rasboras or Chili rasboras)
  • Guppies
  • Platies
  • Swordtails
  • Dwarf Gouramis
  • Otocinclus Catfish

These species exhibit peaceable behavior and can coexist peacefully alongside Corydoras geoffroy.

Tank Mates to Avoid

While Corydoras geoffroy can thrive with numerous peaceful tank mates, it is essential to avoid housing them with aggressive or fin-nipping species. Some examples of unsuitable tank mates include:

  • Cichlids (especially larger or more aggressive varieties)
  • Barbs (such as Tiger barbs or the bright red Rosy barbs)
  • Betta fish (Siamese fighting fish)

These fish may display territorial behavior or nip at the fins of Corydoras geoffroy, causing stress and potential harm.

Corydoras geoffroy Care

Corydoras geoffroy, also known as Geoffroy’s catfish, requires proper care to thrive in an aquarium. Here are some essential tips to ensure their optimal health and well-being.

Care Recommendations

To maintain the best possible health for your Corydoras geoffroy, it is crucial to provide them with a varied diet rich in protein. These fish have a hearty appetite and will appreciate sinking pellets, live or frozen foods such as bloodworms or brine shrimp. Avoid overfeeding them as it can lead to health issues.

Due to their sensitive eyesight, Corydoras geoffroy prefers low-light environments. They are nocturnal creatures that prefer to be active at night. Providing adequate hiding places like plants or caves will make them feel secure and reduce stress levels.

Sensitivity to Salt

It’s important to note that these scaleless fish are highly sensitive to salt. Adding salt directly into the tank can harm them and should be avoided. Instead, focus on maintaining clean water conditions through regular water changes and filtration.

Food & Diet

In the wild, Corydoras geoffroy feeds on a variety of food sources including worms, benthic crustaceans, insects, and plant matter. Mimicking their natural diet in captivity is essential for their overall well-being.

  • Feed them sinking pellets designed specifically for bottom-dwelling fish.
  • Supplement their diet with occasional live or frozen foods such as daphnia or blackworms.
  • Ensure a balanced diet by incorporating vegetable-based foods like spirulina flakes or blanched vegetables.

Feeding Habits

Corydoras geoffroy are opportunistic feeders and will consume various types of food. They readily accept dried foods but also enjoy hunting down live or frozen options. Offering a mix of both will keep them engaged and satisfied.

Now that we’ve covered care recommendations related to feeding habits, sensitivity to salt, and dietary requirements, let’s move on to the next important aspect: common diseases and prevention.

Breeding the Corydoras geoffroy

It’s important to note that while breeding Corydoras geoffroy can be an exciting experience, it requires careful attention to water quality and feeding regimes to ensure successful reproduction.

Recommended Tank Set Up

To successfully breed Corydoras geoffroy, it is important to create the right conditions in their tank. These fish prefer a temperature range of 72-78°F (22-26°C) and require regular water changes to simulate natural fluctuations.

Breeding Process

Male and female Corydoras geoffroy display distinct behaviors during breeding. Females are larger and have a more full-bodied appearance, while males develop pointed fin tips as they mature. When ready to breed, the male will chase the female around the tank in a courtship display.

Once the female is ready, she lays eggs and hold them between her pelvic fins while the male fertilizes them. The number of eggs can range from 2-4 per spawning event.

A separate breeding tank with ideal conditions can increase chances of success

Egg Attachment and Parental Care

After fertilization, the female will attach the eggs to dense vegetation within the tank. Unlike some other species of Corydoras, adult fish do not provide direct protection for their eggs. Instead, they rely on camouflage and dense vegetation for cover.

The incubation period for Corydoras geoffroy eggs typically lasts around 4-7 days before hatching into fry. During this time, it is important to maintain stable water conditions and ensure there is enough food available for both adults and fry.

Fry Care

Once hatched, the fry are relatively self-sufficient but still require proper care. They should be fed small, high-quality foods such as baby brine shrimp or powdered fry food multiple times a day.
