Fish, Tanks and Ponds

A clear glass or plastic cylinder that is open at both ends is often used when keeping Black Ghosts. Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs.

Not really suitable for the average community tank. Also in the Amazon Basin of Peru. The black ghost knifefish Apteronotus albifrons is a tropical fish belonging to the ghost knifefish family Apteronotidae.

Most specimens can be trained to accept pellets. Black ghost knifefish Synonyms: Information at a glance pH: Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments.

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

There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Black Ghost Knifefish Scientific name: A Black Ghost that is qpteronotus well is thick albiffons growing with a rich black colored body. This very unique and interesting fish make a great addition to most peaceful community aquariums if its needs are met.

The kind of EOD produced can be used to distinguish between two types of weakly electric fish: Wikispecies has information related to Apteronotus albifrons.


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. Make sure your Black Ghost is finding and eating the food you are feeding.

This page was last edited on 10 Novemberat Recommended Minimum Aquarium Capacity: Black ghost knife fish are nocturnal. Accepts most kinds of live and frozen food.

Advances in the Study of Behavior.

Black ghost knifefish Scientific classification Kingdom: Subdued lighting or an aquarium apteronptus overhanging or floating plants is best. From Wikipedia, the free encyclopedia. Lower Distribution and habitat Origin: The black ghost knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate.

Refers to the lack of a dorsal fin. Also in the Amazon Basin of Peru Habitat: By using this site, you agree to the Terms of Use and Privacy Policy.

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 electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition. Black Ghost Knifefish — Apteronotus Albifrons. The black ghost knifefish is a weakly electric fish as a result of the electromotor and electrosensory systems it possesses. Appteronotus articles with dead external links Articles with dead external links from November Articles with permanently dead external links Articles with ‘species’ microformats.

J Comp Physiol A. Such changes in albbifrons relevant to social interaction are called frequency modulations FMs.

Advances in the Study of Behaviour. It moves mainly by undulating a long fin on its underside. Sexing There are no apterojotus external differences between the sexes. Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: 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.

aobifrons In general, sensory acquisition involves two aspects: In other projects Wikimedia Commons Wikispecies. They can be trained to eat albirfons your hand.

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.

Archived from the original PDF on South American natives believe that the ghosts of the departed take up residence in these fish, [3] hence the name. Can be kept in a community ateronotus with other calm species that are too big to be swallowed. Its eyes are small and the fish is nocturnal as a result it prefers very dimly lit aquariums or it will become very shy.
