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

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

The electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition.

There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Each species has a characteristic EOD baseline frequency range, which varies with sex and age within the species, as well. Information at a glance pH: Make sure your Black Ghost is finding and eating the food you are feeding. The kind of EOD produced can be used to distinguish between two types of weakly electric fish: 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 albifrosn singly or in groups with or with out other fish.


Provide adequate filtrate along with frequent partial water changes.

Black ghost knifefish Scientific classification Kingdom: Such changes in frequency relevant to social interaction are called frequency modulations FMs. Reviews in Fish Biology and Fisheries. Black Ghost Knifefish — Apteronotus Albifrons. Lower Distribution and habitat Origin: Black ghost knife fish are quite shy and they dislike bright lighting.

Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: Good water quality is a must. Refers to the lack of a dorsal fin. Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments. Juveniles will tolerate each other to a point.

Archived from the original PDF on In general, sensory acquisition involves two aspects: Also in the Amazon Basin of Peru Habitat: 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. A clear glass apteronotuz plastic cylinder that is open at both ends is often used when keeping Black Ghosts.

How many fish tanks do you have? Advances in the Study of Behaviour. This very unique and interesting fish make a great addition to most peaceful community aquariums if its needs are met. It moves mainly by undulating a long fin on its underside. Breeding There are one or two reports of black ghost knifefish breeding in captivity but few details are available. 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.

Advances in the Study of Behavior. Black ghost knifefish Synonyms: Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs.

This fish probably uses a weak electric field surrounding it in-order to navigate and to find food. This page was last edited on 10 Novemberat 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.

Wave-type EODs have a narrow power spectra, and can be heard as a tonal sound, where the discharge rate establishes the fundamental frequency. Cookies This site uses cookies: Gymnotus albifrons, Sternarchus albifrons, Apteronotus passan, Sternarchus lacepedii, Sternarchus maximilliani. Apteeonotus 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.

Also in the Amazon Basin of Peru.
