In general, sensory acquisition albifronx two aspects: Can be kept in a community aquarium with other calm species that are too big to be swallowed. Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs. Advances in the Study of Behavior.

Black ghost knifefish – Wikipedia

This fish probably uses a weak electric field surrounding it in-order to navigate and to find food. Black ghost knifefish are aptteronotus electrogenic with lots of receptors around its head. The electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition.

Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments. Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: Recommended Minimum Aquarium Capacity: Breeding There are one or two reports of black apteroontus knifefish breeding in captivity but few details are available.

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. Retrieved from ” https: Information at a glance pH: A clear glass or plastic cylinder that is open at both ends is often used when keeping Black Ghosts.


The baseline frequency is maintained to be almost constant at stable temperature, but will usually be changed due to the presence of others of apteornotus same species.

Provide adequate filtrate along with frequent partial water changes. Sexing There are no reliable external differences between the sexes. Reviews in Fish Biology and Fisheries. Make sure your Black Ghost is finding and eating the food you are feeding.

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.

How many fish tanks do you have? Black ghost knifefish are generally apteronotuw peaceful with suitable tank mates but they are territorial with there own kind so they should be kept either singly or in groups with or with out other fish.

They can be trained to eat of your hand.

Lower Distribution and habitat Origin: Views Read Edit View history. Not really suitable for the average community tank. By using this site, you agree to the Terms of Use and Privacy Policy. The black ghost knifefish is a weakly electric fish as a result of the electromotor and electrosensory systems it possesses.

In captivity they will accept meaty foods such as prawns, lance fish, blood worms, earth worms and other live or frozen food.

Wave-type EODs have a narrow power spectra, and can be heard as a tonal sound, where the discharge rate establishes the fundamental frequency. The black ghost knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate. A Black Ghost that is eating well is thick and growing with a rich black colored body.


Human uses

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.

Advances in the Study of Behaviour. On the basis of infrared video recordings of black ghost knifefish Apteronotus albifrons feeding on small prey Daphnia magna in the dark, we reconstruct three-dimensional movement trajectories of the fish and prey.

Refers to the lack of a dorsal fin. Accepts most kinds of live and frozen food. Good water quality is a must. Each species has a characteristic Apteronotue baseline frequency albifgons, which varies with sex and age within the species, as well. All articles with dead external links Articles with dead external links from November Articles with permanently dead external links Articles with ‘species’ microformats.

The fish is all black except for two white rings on its tail, and a white blaze on albigrons nose, which can occasionally extend into a stripe down its back.
