Black ghost knifefish, Apteronotus albifrons — Fish, Tanks and Ponds
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. Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom: Accepts most kinds of live and frozen food.
Advances in the Study of Behavior.
Gradual frequency rises in interacting black ghost knifefish, Apteronotus albifrons.
The kind of EOD produced can be used to distinguish between two types of weakly electric fish: There are one or two reports of black ghost 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. Gymnotus albifrons, Sternarchus albifrons, Apteronotus passan, Alnifrons lacepedii, Sternarchus maximilliani.
Juveniles will tolerate each other to a point. Not apteronohus suitable for the average community tank. Black Ghost Knifefish — Apteronotus Albifrons. This very unique and interesting fish make a great addition to most peaceful community aquariums if its needs are met. Recommended Minimum Aquarium Capacity: Apteronotsu ghost knifefish are mildly electrogenic with lots of receptors around its head. This fish apternootus uses a weak electric field surrounding it in-order to navigate and to find food.
How many fish tanks do you have? In captivity they will accept meaty foods such as prawns, lance fish, blood worms, earth worms and other live or frozen food. Each species has a characteristic EOD baseline frequency range, which varies with sex albofrons age within the species, as well. Views Read Edit View history. They can be trained to eat of your hand. Apteonotus 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.
Black ghost knife fish are nocturnal. J Comp Physiol A. The black ghost knifefish Apteronotus albifrons is a tropical fish belonging to the ghost knifefish family Apteronotidae.
Black Ghost Knifefish Scientific name: Black ghost knifefish Scientific classification Kingdom: Subdued lighting or an aquarium with overhanging or floating plants a;teronotus best. A clear glass or plastic cylinder that is open at both ends is often used when keeping Black Ghosts. Wave-type EODs have a narrow power spectra, and can be heard as a tonal sound, where the discharge rate establishes the fundamental frequency. Its eyes are small and the fish is nocturnal as a result it prefers very dimly lit aquariums or it will become very shy.
This page was last edited on 10 Novemberat On the basis of infrared video recordings of black ghost apteronotjs Apteronotus albifrons feeding on small prey Aptrronotus magna in the dark, we reconstruct three-dimensional movement trajectories of the fish and prey.
Can be kept in a community aquarium with other calm species that are too big to be swallowed. Advances in the Study of Behaviour. Make sure your Black Ghost is finding and eating the food you are feeding.
Black ghost knifefish
Sexing There are no reliable external differences between the sexes. On the 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.
Atperonotus electrosensory system of weakly electric fish provides a good model system for studying both these aspects of sensory acquisition.
Most specimens can be trained to accept pellets. Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments. In other projects Wikimedia Commons Wikispecies. Information at a glance pH: 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.
Therefore, the black ghost knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs. The black ghost knifefish is a weakly electric fish as a result of the apteronltus and electrosensory systems it possesses. Also in the Amazon Basin of Peru Habitat: A Black Ghost that is eating well is thick and growing with a rich black colored body. Lower Distribution and habitat Origin: Such changes in frequency relevant to social interaction are called frequency modulations FMs.
