Juveniles will tolerate each other to a point. Subdued lighting or an aquarium with overhanging or floating plants is best.

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

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

This fish probably uses a weak electric field albifronw it in-order to navigate and to find food. Archived from the original PDF on Sensory systems are faced with the task of extracting behaviorally relevant information qpteronotus complex sensory environments.

Breeding There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Retrieved from ” https: Black Ghost Knifefish Scientific name: Black ghost knifefish are mildly electrogenic with lots of receptors around its head. Advances in the Study of Behavior.

How many fish tanks do you have? Most specimens can be trained to accept pellets. The baseline frequency is maintained to albifrona almost constant at stable temperature, but will usually be changed due to the presence of others of the same species. Black ghost knifefish Synonyms: Also in the Amazon Basin of Peru.


Views Read Edit View history. They can be trained to eat of aptsronotus hand. If your Black Ghost is having trouble finding food or eating, feed live brine shrimp or drop live black worms directly in front of it. 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.

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

Lower Distribution and habitat Origin: Wild status The status of wild populations is unknown and apteronouts been evaluated. In other projects Wikimedia Commons Wikispecies.

It moves mainly by undulating a long fin on its underside.

All articles with dead external links Articles with dead external links from November Articles with permanently dead external links Articles with ‘species’ microformats. Wave-type EODs have a narrow power spectra, and can be heard as a tonal sound, where the discharge rate establishes the fundamental frequency. This page was last edited on 10 Novemberat Cookies This site uses cookies: Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: This very unique and interesting fish apteronptus a great addition to most peaceful community aquariums if its needs are met.

Refers to the lack of a dorsal fin. By using this site, you agree to the Terms of Use and Privacy Policy. Accepts most kinds of live and frozen food.

Good water quality is a must.

On the other hand, when low-frequency electric fields are generated by external sources instead of the fish itself, a different class of electroreceptor organs is used for this passive electrolocationcalled ampullary organs.

Apteronotus albifrons Linnaeus Black ghost knifefish Scientific classification Kingdom: The fish is all black except for two white rings on its tail, and a white blaze on its nose, which can occasionally extend into a stripe down its back.


Not really suitable for the average community albiifrons. Its eyes are small and the fish is nocturnal as a result it prefers very dimly lit aquariums or it will become very shy. Information at a glance pH: The black ghost knifefish Apteronotus albifrons is a tropical fish belonging to the ghost knifefish family Apteronotidae.

Apteronotus albifrons, Black ghost : aquarium

In particular, we find that the high-pass filter characteristics of P-type afferent response dynamics can serve as a predictive filter for estimating the future position of the prey as the electrosensory image moves across the receptor array.

Wikispecies has information related to Apteronotus albifrons. Black ghost knifefish are generally quite peaceful with suitable tank mates but they are territorial with there albidrons kind so they should be kept either singly or in groups with or with out other fish.

Also in the Amazon Basin of Peru Habitat: On the basis of infrared video recordings of black ghost knifefish Apteronotus albofrons feeding on small prey Daphnia magna in the dark, we reconstruct three-dimensional movement trajectories of the fish and prey.

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.
