The Elephant Nose fish (Gnathonemus petersii) belongs to the Mormyridae family and is a freshwater species native to the central and western parts of the African continent, specifically found in the Niger River, Ogun River, and Chari River. Named in honor of German zoologist Wilhelm Peters, this unique fish is recognized for its trunk-like mouth, resembling an elephant's nose. While captivating, it requires specialized tank conditions, making it less suitable for beginner aquarists.
In its natural habitat, the Elephant Nose dwells in muddy waters with slow flow and dense plant growth. Its distinct mouth structure allows it to forage for food near the bottom layer. However, in captivity, maintaining stable water parameters is crucial, as the fish is sensitive to changes in water composition. They are particularly susceptible to ammonia and nitrates, emphasizing the need for a robust external filter, regular water changes, and substrate cleaning.
The Elephant Nose possesses a weak electric field, aiding in spatial navigation, locating food, and communication with conspecifics. In the wild, it can reach lengths of up to 35 cm, but in captivity, it typically grows to around 25 cm, with a lifespan of approximately 7-10 years.
Characterized by an elongated and flattened body, the Elephant Nose lacks abdominal fins, and its pectoral fins are rear-facing. Dorsal and anal fins are symmetrically located near the forked caudal fin base. The body exhibits a dark-brown to almost black coloring, with opalescent violet tint under specific lighting. Light-colored, roundish arc-shaped lines connect the dorsal and anal fins.
Caring for Elephant Nose fish requires attention to ideal water conditions, including pH levels of 6.5-7.5 and a temperature range of 26°C-28°C. Due to their nocturnal nature, feeding is recommended after turning off the lights or shortly before. The diet consists mainly of live food, such as bloodworms and tubifex, though some may accept frozen and artificial options.
Keeping Elephant Nose fish in a school of at least 3-4 individuals is advisable, promoting a more comfortable and less aggressive environment. A spacious tank of at least 200 liters with dim lighting and ample shelters, including smooth stones, snags, and suitable tank plants, is recommended. A lid is essential to prevent the fish from jumping out of the water.
Although sexual dimorphism is subtle, it's believed that females are larger with a more rounded abdomen. Breeding in captivity is rare, and most Elephant Nose specimens available for purchase are caught in the wild.
