Gymnotus albifrons, Sternarchus albifrons, Apteronotus passan, Sternarchus lacepedii, Sternarchus maximilliani. 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.

Black Ghost Knifefish — Apteronotus Albifrons. How many fish tanks do you have?

Black Ghost Knifefish – Apteronotus Albifrons

The kind of EOD produced can be used to distinguish between two types of weakly electric fish: Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: Recommended Minimum Aquarium Capacity: Black ghost knife fish are quite shy and they dislike bright lighting. Reviews in Fish Biology and Fisheries.

The black ghost knifefish is a weakly electric fish as a result of the electromotor and electrosensory systems it possesses. The black ghost knifefish natively lives in fast moving, albifronw bottom creeks in a tropical climate.

Information at a glance pH: Subdued lighting or an aquarium with overhanging or floating plants is best.


There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Lower Distribution and habitat Origin: This page was last edited on 10 Novemberat Apteronotus albifrons Linnaeus They are a weakly electric fish which use an electric organ and receptors distributed over the length of their body in order to locate insect larvae.

Wikispecies has information related to Apteronotus albifrons. Archived from the original PDF on Most specimens can be trained to accept pellets.

Black ghost knifefish Scientific classification Kingdom: The electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition.

Not really suitable for the average community tank.

Breeding There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Can be kept in a community aquarium with other calm species that are too big to be swallowed. Views Read Edit View history.

Accepts most kinds of live and frozen food. Black ghost knifefish Synonyms: 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.

Wild status The status of wild populations is unknown and hasn’t been evaluated. They can be trained to eat of your hand. In other projects Wikimedia Commons Wikispecies. A clear glass or plastic cylinder that is open at both ends is often used when keeping Black Ghosts. J Comp Physiol A. Advances in the Apteronotuz of Behaviour. This very unique and interesting fish make a great addition to most peaceful community aquariums if its needs are met.


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.

Good water quality is a must. Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments. In captivity aptronotus will accept meaty foods such as prawns, lance fish, blood worms, earth worms and other live or frozen food. Advances in the Study of Behavior.

From Wikipedia, the free encyclopedia. Refers to the lack of a dorsal fin. Juveniles will tolerate each other to a point.
