Elephant Nose Fish Species Profile and Identification

The Elephant Nose Fish, scientifically referred to as Gnathonemus petersii, is a captivating freshwater fish. Its stunning, distinctive feature, a long trunk-like appendage, is remarkably similar to an elephant’s nose. This versatile species hails from the rivers of West and Central Africa and prefers living in soft, slightly acidic waters.

  • Size: Elephant Nose Fish can grow up to 9 inches  (22.5 cm) in length.
  • Appearance: They exhibit a unique body shape with an elongated nose known as a ‘proboscis’. Their bodies are dark, often black or gray, which helps them blend in with their murky surroundings.
  • Distinctive Features: Their namesake ‘nose’ is indeed their most prominent feature. This ‘elephant nose’ is actually a specialized mouth appendage bearing numerous sensory cells.
  • Lifespan: With proper care and good nutrition, Elephant Nose fish can live 6 to 10 years.

Elephant Nose Fish are beloved for their peculiar charm. However, they’re also known to be shy, nocturnal creatures, making their care slightly more challenging than other aquarium species.

Creating a suitable habitat is crucial to their health and happiness, as well as understanding their unique habits and requirements. Despite their unusual quirks, with the right care, these aquatic marvels can bring a touch of exotic wonder to your fish tank.

Note that identifying the gender of Elephant Nose Fish is almost impossible by merely observing exterior features. However, experts often distinguish between sexes by examining their electric fields, a tricky feat for a beginner aquarist. By fully understanding these fish, we can ensure they thrive within their aquarium homes.

Elephant Nose Fish Supplies

When caring for your Elephantnose fish, you’ll need various supplies to ensure a healthy and happy fish. Initially, you will need a spacious aquarium of at least 66 gallons (250 liters), as these fish require ample space to swim.

  • Aquarium: A 250 L or 66 gallons+ tank.
  • Substrate: Sand is a crucial component for these fishes as they like to burrow.
  • Décor: Using smooth rocks, driftwood and low-lighting plants like Anubias sp., Java fern or Vallisneria creates a natural habitat.
  • Lighting: Go for dim aquarium lighting, since Elephantnose fish are nocturnal creatures.
  • Filter: Invest in a decent filtration system since these fishes prefer clean water.
  • Water heater: Maintain their home within warm tropical temperatures between 73-82°F (23-28°C) using a reliable heater.
  • Water testing kit: To check on water quality regularly.
  • Fish food: Provide a diet primarily of blood worms, mosquito larvae, and even small crustaceans.

Remember, your fish’s well-being depends on how well you can replicate its natural environment. Therefore, purchasing the right supplies from the get-go is crucial. By providing an appropriately sized tank, proper substrate for burrowing, adequate lighting and decor, a reliable filter and heater, and an appropriate diet, you’re setting your Elephantnose fish up for success.

Keeping these supplies at hand will make it easier for you to provide the best care for your Elephantnose fish. With the right tools and knowledge, you can enjoy the fascinating behavior and unique appearance of this incredible fish.

Elephant Nose Fish Tank Setup

Kickstarting your elephant nose fish care journey requires a well-planned and set up tank. This fish is nocturnal, hence, the demand for dim lighting to make it feel safe and secure.

Firstly, you must ensure your aquarium size is adequate. A minimum of 250 liters (66 gallons) is critical for these peculiar swimmers.

Essential items for the tank setup involve:

  • Smooth rocks for hiding,
  • Driftwood for providing shelter,
  • Low-light thriving plants like Anubias sp., java fern, and Vallisneria which keep the environment naturally supportive.

Remember, the elephant nose fish burrows into the substrate with its proboscis-like lower lip. Therefore, it’s vital to have a sand substrate in the tank. Coarse or sharp-edged substrates may injure the fish and hinder their natural feeding mechanisms.

In essence, your elephant nose fish tank setup should imitate their natural habitat as closely as possible. Dark, heavily vegetated with slow-moving water, muddy beds, and plenty of cover, just like the rivers they’re used to. Let’s get started on crafting the perfect home for your elephant nose fish!

Elephant Nose Fish Water Requirements

Elephantnose fish thrive in specific water conditions that closely mimic their natural tropical habitats. Keep in mind water temperatures, hardness, and pH levels are among vital parameters to consider for the health and well-being of your Elephantnose fish.

To mimic natural conditions, keep the water temperature between 73-82°F (23-28°C). A stable temperature is crucial for the well-being of this sensitive species so consider using a heater with an adjustable temperature.

Your fish prefers medium hard water conditions, with a hardness level around 5-15°H. Deep-sea salt mixes available in pet stores can be used to adjust water hardness.

The pH level of the tank water should be slightly acidic to neutral, around 6.0-7.5. Use accurate pH test kits to keep tabs on water acidity.

A handy guide to help you keep track of these parameters is:

Parameter Preferred Range
Temperature 73-82°F (23-28°C)
Hardness 5-15°H
pH Level 6.0-7.5

Remember to keep the water clean and install a reliable filter system. Regular water testing and necessary water changes are fundamental for maintaining optimal living conditions for your Elephantnose fish.

Lastly, accommodate these fish in a tank of a minimum of 250 liters (66 gallons), allowing enough room for swimming and exploration. Your fish will appreciate it!

Elephant Nose Fish Diet and Feeding

One of the key elements of Elephant Nose fish care is understanding their dietary habits. As an omnivorous species, a varied diet is important for keeping them healthy. This includes nutritional foods like live or frozen food such as brine shrimp and bloodworms. 

It’s also important to know that they do enjoy eating small amounts of plant matter.

  • Remember to feed them in small amounts, but frequently. Elephant Nose fish likes to eat throughout the day, so breaking their meals into several smaller portions is optimal.
  • Night feeding is also vital, because they are a nocturnal creature. Scheduling at least one feeding session after the lights out can help mimic their natural feeding times.

Additionally, consider investing in a high-quality, slow-sinking pellet or flake food that is specifically designed for Elephant Nose fish. This ensures they have access to a balanced diet rich in valuable nutrients. Despite their flexibility in diet, they can’t survive on simple flake food alone, as it doesn’t provide all the vitamins and minerals they need.

Providing a well-balanced diet for your Elephant Nose fish is a certain path to ensuring their longevity and health. Lastly, remember not to overfeed your fish, as excess food can degrade water quality and lead to health problems. Just like any other pet, a balanced, varied diet is an important aspect of care that shouldn’t be overlooked.

Elephant Nose Fish Care Schedule

Caring for an Elephant Nose Fish doesn’t have to be daunting. By understanding its habits, needs, and behaviors, you can create a schedule that keeps your aquatic pet happy.

Firstly, remember it’s a nocturnal fish. So, be sure to provide food during the evening or night. Place the dinner directly in its path, considering it has a poor vision and primarily uses electrical fields to navigate.

Daily tank checks

  • Monitor the water temperature, ensuring it’s between 73-82°F (23-28°C).
  • Regularly check the pH levels should be between 6.0 and 7.5, to maintain stability within its comfort zone.
  • Ensure the tank’s lighting isn’t too bright as it can make your fish uncomfortable.

Weekly tasks

  • Cleaning the tank to remove waste and uneaten food,
  • Checking the overall health of the fish,
  • Making sure the plants and hiding places are still safe and secure.

Monthly tasks

  • Testing water hardness, ideally, it should be 5-15°H,
  • Checking the filter to see if it needs replacing.

This schedule will ensure your Elephant Nose Fish thrives in its environment and remains in good health. By following this care routine, you’re showing your commitment to its wellbeing.

Elephant Nose Fish Health Problems

Despite being a hardy fish, the Elephant Nose Fish can encounter specific health issues that you need to be aware of as an owner. Common health troubles include parasitic infections, bacterial infections, and mouth damage.

  • Parasitic Infections: These are typically caused by poor water conditions. Signs of parasitic infection might include weight loss, decreased appetite, and unusual swimming behavior.
  • Bacterial Infections: Like parasites, bacterial issues rise from poor water quality. Bacterial infections often showcase bloated body, sores, and sometimes, a cloudy eye.
  • Mouth Damage: This generally happens due to improper substrates. As they love burrowing, sharp-edged or coarse substrates can harm their mouthparts, even hampering natural feeding.

Ensure that you’re maintaining the optimum water conditions and providing them with the right diet to prevent these health problems from developing. You might not become a fish health expert overnight, but consistent observation and care can significantly reduce the chances of these issues. 

Elephant Nose Fish Tank Mates

Elephant nose fish are quite peaceful, but also very unique and can be a bit finicky about their companions. Choosing the right tank mates is crucial for their well-being.

  • Species that are overly territorial or prone to nipping may stress the elephant nose fish, potentially leading to health problems.
  • Larger, aggressive fish are definitely out, as they may see the slow-moving elephant nose as a meal.

The best tank mates for your elephant nose fish are generally peaceful, non-aggressive species. Some examples include:

  • Corydoras: These bottom-dwelling catfish can share the lower levels of the tank without causing trouble.
  • Glass Catfish: Their peaceful nature and distinctive appearance could make a nice contrast to your elephant nose.
  • Bristlenose Plecos: They are generally peaceful and won’t bother your elephant nose fish.

Always observe the interactions between your fish closely, especially in the beginning. Each fish has its own personality, and what works for one may not work for another.

Enjoy setting up your elephant nose fish tank with the perfect companions, offering them a serene home. Your elephant nose fish will appreciate these friendly tank mates and will reward you by showing off its unique traits and behaviors.

Elephant Nose Fish Breeding

Breeding Elephant nose fish can be a challenging endeavor due to their complex mating behaviors. The key obstacle to successfully breeding these fish in captivity arises from their unique communication system.

They communicate via electric fields, a method not fully understood nor replicable by aquarists. Sex determination in these fish also requires analysis of these electric fields, a task best left to experts. This makes it difficult for an average aquarium enthusiast to distinguish males from females, let alone breed them.

One study indicates that life under aquarium confines may distort the sexual identification cues expressed in their electric fields. This implies, your fish might not even recognize potential mates of the opposite sex in your tank!

As a result, it’s generally assumed that breeding these fish is not feasible for the regular hobbyist. While it might seem disappointing, the silver lining is, you can sidestep the breeding-related complications with this species, focusing more on providing them optimum care and a engaging environment.

If you’re considering starting a home aquarium with elephant nose fish:

  • Understand that breeding these species in captivity is tremendously challenging and possibly not feasible.
  • Focus on their well-being and maintaining good tank conditions.
  • Never push them into a pressured breeding scenario, which can stress the fish.

The lack of breeding shouldn’t dissuade you from keeping these fascinating creatures. With nurturing care, they can thrive in your tank, captivating you with their uniqueness.


With the right care and attention, your Elephant Nose fish can thrive in your home aquarium. It may seem like a lot to consider, but once you get the hang of it, you’ll find great joy in watching them.
