Long Nose Elephantnose Fish (Campylomormyrus numenius)
The Long Nose Elephantnose Fish is a rare and highly specialized African species known for its elongated, trunk-like snout used to detect food through weak electrical signals. Its sleek body and unique sensory abilities make it a fascinating centerpiece for advanced aquarists. Sensitive to water quality and environment, this species thrives only under stable, well-maintained conditions.
Max Size:
Up to ~9–10 inches (23–25 cm)
Tank Size:
Minimum 75–125 gallons; requires a calm, dimly lit aquarium with soft substrate and excellent water quality
Tank Mates:
Best kept with peaceful, non-aggressive fish such as:
- Congo tetras
- Synodontis catfish
- Other mild-mannered African species
Avoid fin-nippers, aggressive fish, or overly active species that may outcompete it for food.
Diet:
Carnivorous; prefers:
- Bloodworms
- Blackworms
- Insect larvae
- Frozen meaty foods
May take high-quality sinking foods, but live or frozen foods are often necessary.
Additional Notes:
Highly sensitive to poor water conditions and sudden changes. Uses electroreception to navigate and feed, so avoid housing with overly competitive feeders. Best kept in groups only in very large, carefully managed aquariums, as they can be territorial.
