It’s crucial to comprehend the unique needs and maintenance requirements of a Nile elephant if you’re thinking about bringing one into your aquarium. With the correct conditions and care, this amazing fish can make a fascinating addition to your aquatic ecosystem.

Habitat

It is found throughout the central and western regions of Africa; reports of it have been made in the Chari, Ogun, and Niger rivers in Zambia, Mali, Benin, Niger, Nigeria, Chad, Central African Republic, Cameroon, and Republic of Congo. prefers areas of rivers that are heavily vegetated, have little current, and have murky, dark water.

Description

The body is compressed from the sides, making it longer. The dorsal and anal fins are symmetrical and situated nearly at the base of the forked tail, while the ventral fins are absent. The pectoral fins are raised high. The caudal fin joins the body at a very narrow point.

The fish is distinguished by its "mouth," which is actually its lower lip shaped like a proboscis, giving it an elephant-like appearance.

Because of its numerous nerve endings and ability to generate weak electrical impulses, this organ enables the fish to sense danger, find food, and navigate through murky, dark water.

The skin tone is a deep brown that verges on black. It may shimmer with purple tones in certain lighting conditions. Two thin, rounded arcs connect the anal and dorsal fins on either side.

Sexual differences are not well communicated. The abdomens of females are more rounded and larger.

Size

It can reach a maximum size of 25 cm in the wild, but in a backyard pond, it typically stays no larger than 15 cm.

Aquarium

It is necessary to have a large aquarium; the ideal dimensions for an aquarium are 100x45x45 cm, or 200 liters. The larger the fish community, the larger the aquarium capacity should be.

For the Elephant Fish to feel secure, dim or weak lighting is necessary. Shelters are necessary, and the quantity of them should equal or surpass the number of fish. Smooth stones, snags, and low-light-tolerant plants, like anubias and Microsorium fern, can also be employed.

Sand or another type of soft soil will be needed as a substrate, which is essential for the survival of this species because otherwise the fish may injure their lower lip, which resembles a trunk and will make it harder for them to eat. An aquarium with a lid is essential so that fish can jump out of the water.

Water parameters:

23–28 °C, pH 6.0–7.5, DGH 5–15.

Aeration-based filtration is necessary; it is highly dependent on the water’s quality, and a third of the filter needs to be changed every week.

A slime fish is vulnerable to several aquarium medications, including salt, just like other "naked" fish.

Behavior and compatibility

Tranquil and serene, yet possessive perspective. Incompatible with nearly all tropical fish, intraspecific conflicts are unavoidable due to a shortage of living space. They won’t be able to compete with highly active or aggressive fish species when feeding, so they shouldn’t be kept with them.

They should be kept in groups of at least three to four people, but five or more is preferable. The fish are more at ease and less likely to become aggressive in a larger group of relatives.

It is appropriate to have other African species in the biotope community, such as Ctenopoma, Congo tetra, Butterflyfish, and Synodontis.

Additionally, they get along well with certain species of Geophagus, angelfish, and calm cichlids.

Gnathonemus petersii, the Nile elephant fish, is an intriguing and unusual freshwater species distinguished by its long, trunk-like snout and capacity to sense its environment through the use of electric fields. Because of its unique appearance and fascinating behavior, this fish is well-liked by aquarium enthusiasts; however, because of its delicate nature and particular environmental requirements, it needs extra care.

Feeding

They are very laid back and will eat dried, frozen, and live food in an aquarium. They favor tubifex, or bloodworms.

Small pieces of meat or lean fish can occasionally be used to add variety to the menu. Food is gathered at the bottom, thrown up first, and then sucked in.

It’s crucial to make sure they get enough food because they are a relatively sluggish fish and cannot compete with their more active neighbors in the food chain.

The fascinating and unusual species known as Gnathonemus petersii, or the Nile elephant, can add an element of the extraordinary to any aquarium. They can be distinguished from other fish by their remarkable electrical abilities and unusual trunk-like mouth.

Even though they might need a little more care and attention, particularly when it comes to feeding and tank setup, their fascinating behavior and relationship with their surroundings make keeping them as pets a rewarding hobby for committed aquarists. These fish do best in a peaceful, well-kept aquarium where they are free to explore and behave as they would naturally.

Maintaining a Nile elephant can be a rewarding and instructive experience for those who are prepared to put in the necessary time and work. A glimpse into the wonders of aquatic life can be gained by observing their intelligence and distinctive manner of navigating their environment.
