Subdued lighting or an aquarium with overhanging or floating plants is best.

Not really suitable for the average community tank. 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.

Wikispecies has information related to Apteronotus albifrons. Retrieved from ” https: The black ghost knifefish Apteronotus albifrons is a tropical fish belonging to the ghost knifefish family Apteronotidae. Black ghost knifefish are generally quite peaceful with suitable tank mates but they are territorial with there own kind so they should be kept either singly or in groups with or with out other fish.

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

Juveniles will tolerate each other to a point. 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.

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

Fish Plants Shrimp Snails Frogs. Wild status The status of wild populations is unknown and hasn’t been evaluated. Refers to the lack of a dorsal fin.

Gymnotus albifrons, Sternarchus albifrons, Apteronotus passan, Sternarchus lacepedii, Sternarchus maximilliani. Recommended Minimum Aquarium Capacity: The black ghost knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate.

Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments. 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.

Also in the Amazon Basin of Peru. Black ghost knifefish are mildly electrogenic with lots of receptors around its head.

Apteronotus albifrons, Black ghost : aquarium

It moves mainly by undulating a long fin on its underside. Their tank should be dimly lit and there should be caves for them to hide in, pieces of pipe of the right apternootus are readily accepted for this. Black ghost knife fish are nocturnal. The kind of EOD produced can be used to distinguish between two types of weakly electric fish: Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs.

Black Ghost Knifefish – Apteronotus Albifrons

Accepts most kinds of live and frozen food. Sexing There are no reliable external differences between the sexes. Female black ghost knifefish generate EODs at a higher frequency than albiffrons males, an FM which can be used for gender recognition.

Black ghost knifefish Albiffrons The black ghost knifefish is a weakly electric fish as a result of the electromotor and electrosensory systems it possesses.

We combine the reconstructed trajectory information with models of peripheral electric image formation and primary albiforns afferent response dynamics to estimate the spatiotemporal patterns of transdermal potential change and afferent activation that occur during prey-capture behavior.

This very unique and interesting fish make a great addition to most peaceful community aquariums if its needs are met.

A clear glass or plastic cylinder that is open at both ends is often used when keeping Black Ghosts. Such changes in frequency relevant to social interaction are called frequency modulations FMs. J Comp Physiol A. Cookies This site uses cookies: Apteronotus albifrons Linnaeus 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. Each species has a characteristic EOD baseline frequency range, which varies with sex and age within the species, as well.
