black ghost knifefish living habits
The wire-fed electric eel is mild-mannered, but aggressive, and likes nocturnal life. Most of the time, they hide in the dark environment of densely planted water and grass, crevices of rocks and sinking trees. It relies on the weak current in the body to accurately sense water flow, obstacles, food, etc.
The swimming method is to rely on the wavy swing of the long tail fin to move forward and backward, sometimes swimming upright, and sometimes sleeping on the back. The eyes are degraded, and they can barely see anything and can only sense light and dark, but the body emits weak radio waves that function like radar, and rely on it to “see” the surrounding environment.
The name “devil” highlights its mystical properties. Except for the breeders themselves, no one will notice their presence in the aquarium. Occasionally during the day they swim upright and slide across the aquarium, like a black ghost that suddenly appears.
The eyes of the electric eel have been degraded, but it is still able to traverse the aquarium extremely sensitively with the help of its wide anal fins and paddle-like caudal fins by emitting a special weak current and a sensitive sense of smell. The dexterous and wonderful swimming posture is like a black feather dancing in the wind. There are very few fishes that can compete with the swimming posture of the black devil, which is the attractive charm of the black devil.
black ghost knifefish rearing
Electric eels like nocturnal sex and it is difficult to identify males and females. They are oviparous fish and are very difficult to reproduce. They require uniquely designed aquariums and harsh breeding conditions to successfully reproduce. The suitable water temperature is 23~27℃, which is more sensitive to water quality, suitable pH: PH 6.5-7.2, suitable hardness (dGH): 4-12°N. They are extremely strong and rarely get sick. Black devils like to eat live animal bait, such as water worms and red worms. But it is also very easy to accept all kinds of artificial bait. But it has a fierce name, but it is gentle and can be mixed with most tropical fish. However, adult fish will eat small fish, so special attention must be paid to it.
