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. Reviews in Fish Biology and Fisheries.

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. They can be trained to eat of your hand. Juveniles will tolerate each other to a point.

Recommended Minimum Aquarium Capacity: Lower Distribution and habitat Origin: Provide adequate filtrate along with frequent partial water changes. Gymnotus albifrons, Aptreonotus albifrons, Apteronotus passan, Sternarchus lacepedii, Sternarchus maximilliani. Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments.

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.

Such changes in frequency relevant to social interaction are called frequency aobifrons FMs.

Black ghost knifefish

Black Ghost Knifefish Scientific name: Black ghost knifefish Synonyms: Refers to the lack of a dorsal fin. Each species has a characteristic EOD baseline frequency range, which varies with sex and age within the species, as well. Black ghost knifefish are mildly electrogenic with lots of receptors around its head. South American natives believe that the ghosts of the departed take up residence in these fish, [3] hence the name. The black ghost knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate.

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: Their tank should be dimly lit and there should be caves for them to hide in, pieces of pipe of the right diameter are readily accepted for this.


The black ghost knifefish Apteronotus albifrons is a tropical fish belonging to the ghost knifefish family Apteronotidae.

Human uses

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.

Black ghost knifefish Scientific classification Kingdom: It moves mainly by undulating a long fin on its underside. Breeding There are one or two reports of black aapteronotus knifefish breeding in captivity but few details are available. Subdued lighting or an aquarium with overhanging or floating plants is apteromotus.

Its eyes are small and the fish is nocturnal as a result it prefers very dimly lit aquariums or it will become very shy. The electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition.
