Black ghost knifefish Scientific classification Kingdom: 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.
Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs. Wikispecies has information related to Apteronotus albifrons.
Make sure your Black Ghost is finding and eating apteronogus food you are feeding. J Comp Physiol A. There are one or two reports of black ghost knifefish breeding in captivity but few details are available.
Black ghost knifefish
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. Each species has a characteristic EOD baseline frequency apteronogus, which varies with sex and age within the species, as well.
Black Ghost Knifefish — Apteronotus Albifrons.
Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: The electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition. Reviews in Fish Biology and Fisheries. Black ghost knifefish are mildly electrogenic with lots of receptors around its head. Accepts most apterronotus of live and frozen food.

Female black ghost knifefish generate EODs at a higher frequency than the males, alnifrons FM which can be used for gender recognition. Lower Distribution and habitat Origin: 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 baseline frequency is maintained to be almost constant at stable temperature, but will usually be changed due to the presence of albifrona of the same species.

Gradual frequency rises in interacting black ghost knifefish, Apteronotus albifrons.
Cookies This site uses cookies: Also in the Amazon Basin of Peru Habitat: Juveniles will tolerate each other to a point. Not really suitable for the average community tank. On apbifrons 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.
Also in the Amazon Basin of Peru.
If your Black Ghost is having trouble finding food or eating, feed live brine shrimp or drop live black worms directly aptetonotus front of it. South American natives believe that the ghosts of the departed take up residence in these fish, [3] hence the name. Black ghost knife fish are nocturnal.
Gradual frequency rises in interacting black ghost knifefish, Apteronotus albifrons.
It moves mainly by undulating a long fin on its underside. They are a weakly electric fish which use an electric organ alnifrons receptors distributed a;teronotus the length of their body in order to locate insect larvae. 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.
Gymnotus albifrons, Sternarchus albirons, Apteronotus passan, Sternarchus lacepedii, Sternarchus maximilliani. This page was last edited on 10 Novemberat Wild status The status of wild populations is unknown and hasn’t been evaluated. Advances in the Study of Behaviour. Archived from the original PDF on Can be kept in a community aquarium with other calm species that are too big to be swallowed.
Retrieved from ” https: 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. Subdued lighting or an aquarium with overhanging or floating plants is best. Black Ghost Knifefish Scientific name: A Black Ghost that is eating well is thick and growing with a rich black colored body.
Good water quality is a must.
