Corydoras narcissus prefer living in groups or schools where they feel safer and more secure. They have adapted to their bottom-dwelling nature by developing barbels around their mouths which help them navigate and search for food on the substrate.

Size, Growth Rate & Lifespan

With a maximum standard length of 3 inches, these corydoras are relatively small fish compared to other species. They have a slow growth rate but can live for an average of 5 to 10 years if provided with proper care and a suitable environment.

Habitat & Tank Conditions

To provide a suitable environment for the Corydoras narcissus, it is essential to have a spacious tank with plenty of floor space.

Tank Size & Set Up

A tank size of at least 20 to 30 gallons is recommended to accommodate these active fish comfortably. It’s crucial to ensure that there is ample room for them to swim and explore.

Regular water changes are necessary to maintain optimal water quality in the aquarium. This helps remove any accumulated waste or toxins, keeping the water conditions pristine for the fish. Aim for weekly or biweekly water changes, replacing about 25% of the tank’s volume each time.

Water Parameters

Maintaining appropriate water parameters is vital for the well-being of Corydoras narcissus. These freshwater fish thrive in temperatures ranging from 72°F to 78°F (22°C to 26°C). It’s important to monitor and regulate the temperature within this range using a reliable aquarium heater.

In terms of pH levels, Corydoras narcissus prefer slightly acidic to neutral conditions, with a pH range between 6.5 and 7.5 being ideal. Monitoring and adjusting the pH level using appropriate buffers can help create a suitable environment for these fish.

Substrate & Decor

Providing suitable substrate and decor is crucial when setting up an aquarium for Corydoras narcissus. These fish appreciate having hiding spots like caves or plants where they can seek shelter when needed. Utilizing the right amount of soft sand or fine gravel as substrate mimics their natural habitat and allows them to exhibit their natural behaviors such as sifting through the substrate in search of food.

Adding live plants not only enhances the aesthetic appeal but also provides additional hiding places while contributing to improved water quality by absorbing excess nutrients. It’s important to choose plant species that thrive in similar water conditions as Corydoras narcissus.

Behavior

Corydoras narcissus is well-known for its non-aggressive nature and its tendency to shoal together. These fish thrive when they have company and feel secure in their environment. They spend most of their time exploring the bottom of the tank, scavenging for food and interacting with each other.

Compatible Tank Mates

When selecting tankmates for corydoras narcissus, it’s essential to choose peaceful community fish that won’t intimidate or harm them. Some suitable companions include:

Tetras: Species like neon tetras or ember tetras can coexist peacefully with corydoras narcissus.

Guppies: These colorful fish make great tankmates due to their peaceful nature.

Rasboras: Harlequin rasboras or chili rasboras are excellent choices that will get along well with your corydoras.

In addition to these options, other bottom-dwelling species like loaches or catfishes can be compatible tank mates for corydoras narcissus. Just ensure that the tank provides enough hiding spots and ample space for all inhabitants.

Tank Mates to Avoid

It’s crucial to avoid introducing aggressive or fin-nipping species into the same tank as corydoras narcissus. Such species may stress out or harm these gentle creatures. Some examples of unsuitable tank mates include:

Cichlids: Aggressive cichlid species may see corydoras as potential prey or competitors.

Barbs: Fin-nipping barbs can cause significant damage to the delicate fins of corydoras.

Betta Fish (Siamese Fighting Fish): Betta fish are known for their territorial behavior and may attack corydoras.

By avoiding these incompatible tank mates, you can ensure a harmonious and stress-free environment for your corydoras narcissus.

Corydoras narcissus Care

Corydoras narcissus, also known as the Narcissus Catfish, requires proper care to thrive in your aquarium.

Care Recommendations

To ensure the well-being of your long nosed cory, it is crucial to maintain a clean and healthy environment for them. This can be achieved by following these care recommendations:

It is essential to have a well-maintained filtration system in place. This will help keep the water clean and free from harmful substances.

Regular monitoring of ammonia, nitrite, and nitrate levels using test kits is necessary. These parameters should be kept within safe limits to prevent any potential harm to your fish.

Diet & Nutrition

Proper nutrition plays a vital role in the overall health of your Corydoras narcissus. Feed them high-quality sinking pellets that are specifically formulated for bottom-dwelling fish like Corydoras. Frozen foods such as bloodworms or brine shrimp can also be included in their diet.

Breeding the Corydoras narcissus

To successfully breed Corydoras narcissus, it is important to create the right tank setup and provide suitable conditions for breeding. The following points will guide you through the process:

Recommended Tank Set Up

  • Temperature and Water Conditions: Corydoras narcissus prefer slightly warmer temperatures ranging from 75°F to 80°F (24°C to 27°C). Soft water with a pH level between 6.0 and 7.0 is ideal.
  • Spawning Surfaces: Provide broad leaves or spawning mops in the tank. These flat surfaces will serve as deposition sites for the eggs. Ensure that these surfaces are easily accessible for the fish.

Breeding Process

  • Male’s Role: Male Corydoras narcissus play an essential role in fertilizing the eggs. During mating, they embrace females tightly and release sperm over the deposited eggs.
  • Nest Guarding: After fertilization, males guard the nest to protect it from potential threats. They diligently watch over the eggs until they hatch.

Fry Care

  • Separation of Adults: To prevent predation, it is crucial to separate adult Corydoras narcissus from their eggs or fry. This can be done by moving them to a separate tank or using dividers within the same tank.
  • Feeding Fry: Once hatched, fry should be fed with small-sized foods such as baby brine shrimp or powdered flake food until they are large enough to consume larger particles.

Breeding Corydoras narcissus can be a rewarding experience for aquarists looking to expand their collection of corys. By providing suitable conditions and closely monitoring their behavior, you can increase your chances of successful breeding.
