This fish probably uses a weak electric field surrounding it in-order to navigate and to find food.

Black ghost knifefish

Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its albifrlns corresponding receptor organs. Wikispecies has information related to Apteronotus albifrons. Wild status The status of wild populations is unknown and hasn’t been evaluated. Sexing There are no reliable external differences between the sexes.

Black ghost knifefish Scientific classification Kingdom: Apteronotus albifrons Linnaeus If alibfrons Black Albicrons is having trouble finding food or eating, feed live brine shrimp or drop live black worms directly in front of it.

Lower Distribution and habitat Origin: Gymnotus albifrons, Sternarchus albifrons, Apteronotus passan, Sternarchus lacepedii, Sternarchus maximilliani.

Female black ghost knifefish generate EODs at a higher frequency than the males, an FM which can be used for gender recognition.

The black ghost knifefish is a weakly electric fish as a result of the electromotor and electrosensory systems it possesses. Advances in the Study of Behavior.


Gradual frequency rises in interacting black ghost knifefish, Apteronotus albifrons.

Each species has a characteristic EOD baseline frequency range, which varies with sex and age within the species, as well. Cookies This site uses cookies: All articles with dead external links Articles with dead external links from November Articles with permanently dead external links Articles with ‘species’ microformats.

The black ghost knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate. There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Black Ghost Knifefish — Apteronotus Albifrons.

We characterize the behavioral strategies used by the fish, with emphasis on the functional importance of the dorsal edge in prey capture behavior, and we analyze the electrosensory consequences.

Most specimens can be trained to accept pellets. The role these FMs have in communication is significant, as black ghost knifefish have developed jamming avoidance responseswhich are behavioral responses that avoid the overlapping of EOD frequencies between conspecific individuals to prevent sensory confusion.

A clear glass or plastic cylinder that is open at both ends is often used when keeping Black Ghosts. This page was last edited on 10 Novemberat Breeding There are one or two reports of black ghost knifefish breeding in captivity but few details are available.


Juveniles will tolerate each other to a point. Archived from the original PDF on Retrieved from ” https: In general, sensory acquisition involves two aspects: Can be kept in a community aquarium with other calm species that are too big to be swallowed. Subdued lighting or an aquarium with overhanging or floating plants is best. Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: We combine the reconstructed trajectory information with models of peripheral electric image formation and primary electrosensory afferent response dynamics to estimate the spatiotemporal patterns of transdermal potential change and afferent activation that occur during prey-capture behavior.

The black ghost knifefish Apteronotus albifrons is a tropical fish belonging to the ghost knifefish family Apteronotidae. In other projects Wikimedia Commons Wikispecies. Good water quality is a must. The baseline frequency is maintained to be almost constant at stable temperature, but will usually be changed due to the presence of others of the same species.

On the basis of infrared video recordings of black ghost knifefish Apteronotus albifrons feeding on small prey Daphnia magna in the dark, we reconstruct three-dimensional movement trajectories of the fish and prey.

Fish Plants Shrimp Snails Frogs. Black ghost knifefish are mildly electrogenic with lots of receptors around its head.
