Easy Keeping and Easy Breeding.

I originally bought these as part f the "Nightmare" series from Japan, but you will be able buy them separately here at www.aquazone.com. If your looking for the Japanese Nightmare Series you can find them at www.himeya.com either way they will add a bit of sparkle to your tanks.

Info

Family: Mormyridae (Elephantfishes) picture (Gnpet_u1.jpg) by Moreau, J.

Order: Osteoglossiformes
Class: Actinopterygii (ray-finned fishes)
FishBase name: Elephantnose fish
Max. size: 35.0 cm SL (male/unsexed; Ref. 2915)
Environment: demersal; freshwater; pH range: 6.0 - 8.0; dH range: 5.0 - 19.0
Climate: tropical; 22 - 28°C
Importance: fisheries: subsistence fisheries; aquarium: commercial
Distribution:
Gazetteer West Africa: from Niger to Congo River basins. Limited to the Lower Niger, in the Ogun, in the Cross River Basin and in the Upper Chari.
Diagnosis: Dorsal spines (total): 0-0; Dorsal soft rays (total): 25-31; Anal spines: 0-0; Anal soft rays: 32-36.
Biology: Occurs close to the bottom where it probes for food with the long snout. Territorial and usually aggressive towards members of its own species. This behavior has been shown to involve electric organ discharge (EOD) activity (Ref. 10011). Feeds mostly at night on worms and insects (Ref. 7020), probably aided by electrosensory inputs (Ref. 10011). Electroreceptors are distributed over the entire head, the dorsal and ventral regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011). Sex-related EOD characteristics in this species has been demonstrated in the laboratory with freshly imported samples during the breeding season; such EOD dimorphism changed with time in captivity (Ref. 10764; 10766). Lead nitrate in water significantly increased EOD rate and selectively altered the EOD waveform of this species (Ref. 10469). Dubbed a `hearing specialist' having auditory abilities in the range of 100-2500 Hz, with `best frequencies' between 300 and 600 Hz (Ref. 10830).
Red List Status: Not in IUCN Red List , (Ref. 36508)
Dangerous: harmless
