Elephant Nose Fish Habitat
Exotic Elephant Nose Fish is also known as the Nile elephant, or Peters elephant lives in the wild in the freshwater rivers of Africa, namely in the reservoirs of the central and western parts of the mainland.
Elephant Nose Fish prefers to settle closer to a silty, densely overgrown with grass bottom. Even better, if among the vegetation, many snags and logs act as shelters.
Elephant Nose Fish Appearance
It should be noted that the Nile elephant is not a very large fish. In nature, it grows up to 22 cm, and in an aquarium, you can rarely find an individual longer than 15 cm. Due to life in muddy water, elephant fish has a dark, almost black color appearance. On its flattened lateral trunk, there is no scale, which makes it look velvety.
The ventral fins of this fish are absent, and the pectoral fins are located rather high. The dorsal and anal fins are opposite each other, almost at the tail itself, which is connected to the body through a narrow transition.
Only two light strips adorn the dark skin of the fish. They are located on both sides of the body and stretch from the dorsal fin to the anal.
A distinctive feature of the fish is the lower lip, which is much longer than the upper lip and resembles the trunk of an elephant. It is thanks to this structure of the oral apparatus that fish quickly obtain food from silt.
The eyes of the elephant Peters are rather poorly developed. This is due to the fact that the fish prefers a nocturnal lifestyle.
Therefore, an organ that is located on the tail and produces weak electrical impulses helps to search for food, a partner, and also to explore the terrain to the elephant. They are captured by electroreceptors located on the head of the fish, and they help create a picture of the world.
Elephant Nose Fish or Peters’s elephant is not too careless so that it can be recommended both for beginner aquarists and experienced specialists.
The main thing in caring for this fish is to create conditions that are most suitable for it :
- The size of the aquarium – It should be noted that for elephant fish requires a reasonably large living space. So, for one individual, an aquarium with a volume of at least 200−250 liters is suitable, and to make the fish feel comfortable, it is recommended to start a flock of 5-7 “elephants.” Therefore, the aquarium should be appropriate.
- Water parameters – These fish live in nature in warm bodies of water, so special attention should be paid to the temperature in the aquarium. It should be between +23 and +28 degrees.We must not forget about the hardness of water (5-15 units) and acidity (6.5-7 units). Elephant Nose Fish are susceptible to chemicals, so you should install a fairly powerful filter, replace the third part of the water in the aquarium once every seven days with fresh. Regularly need to siphon the bottom, removing food residues and traces of the pet’s vital activity.
- Aquarium Decoration – Since the elephant fish collects food from the bottom, looking for it with the help of its “trunk,” the best solution would be to use river sand or polished gravel with peat crumb as soil.But be sure to carefully check it so that it does not have sharp stones or any foreign objects that could injure the mouthpiece of this exotic fish. At the bottom, you need to put so many shelters so that there are more of them in quantity than the fish themselves. Otherwise, fights between the pets cannot be avoided.
Lighting is better to choose dim, as Peters elephants prefer to lead a nocturnal lifestyle. Also, these fish are susceptible to antibiotics, ammonia, and nitrites. Therefore, a filter in the aquarium needs a reasonably powerful, but not creating a strong current, which Peters elephants can not stand.
Be sure to equip the aquarium with a lid, as the fish quite often jump into the wild. It is essential to consider that the Nile elephants are incredibly harmful about metal objects, which, because of this, are best not to be used as decorative elements.
Elephant Nose Fish Feeding
Peters elephants are happy to eat both live and frozen and dried food. During feeding, all pets must have enough food.
The problem may arise since Peters elephants are not too mobile and too peaceful; they will never fight for food with other inhabitants of the aquarium. Quite often, you can see how the owner feeds his pets with tweezers, offering an individual piece to each elephant.
These are the most requirements that should be observed when keeping Nile elephants. Having prepared the aquarium and keeping the fish in quarantine, you can safely transfer the acquired pets to a permanent place of residence.
Elephant Nose Fish Tank Mates
Elephant fish are very peaceful. They get acquainted with other inhabitants of the aquarium quite interestingly – they gently touch them with their “trunks” without causing harm.
But the elephants themselves can easily offend other large predators.
The best tankmates are :
- African butterfly fish;
- synodontis cuckoo;
- synodontis veiled;
- Congo fish
- Tetra Fish
- Small Bichirs
- Discus Fish
- Angelfish, etc
These fish will never offend the elephant Peters and will be able to get on well with him.
Quite often, novice aquarists are concerned about the fact that the Nile elephants produce electrical impulses, which theoretically can injure small fish. This is ruled out. Elephants have too low electrogenicity, so they are unable to harm anyone.
Sexual dimorphism and Captive Breeding
Nile elephants belong to the category of fish in which sexual dimorphism is practically not expressed. Females differ from males only in that they are slightly larger and have a rounded abdomen.
In principle, the gender of the acquired pet is not very important, since it is not possible to get offspring in captivity from Nile elephants. Scientists have not yet fully understood the reason. They suggest that in an aquarium, the electrical impulses emanating from the fish are distorted.
As a result, males and females cannot locate each other. But so far, this is only a theory. Perhaps soon, scientists will be able to study these unusual exotic fish better, and then get offspring from them.
Thus, both specialists and beginner aquarists should not be afraid to buy Nile elephants. If you buy a healthy fish and adequately care for it, then it will be able to please its owner for many years because, in captivity, pets live for at least ten years.
