Black Ghost Knifefish 8cm

This is one beautiful elegant fish. The fish has nocturnal habits. During the day time it is rather timid and quite often stays in a shelter on a tank bottom. So it is extremely important to provide places of shelter.  The Black Ghost like rather low lighting and has poor eye sight because of this and to compensate theh shortness of vision it generates a low electrical field around itself.  This enables them to sense movement and define objects.

The fish doesn't have abdominal and dorsal fins, though its anal fin is rather well developed and it stretches from the fish head to its tail. Due to waving motion of the anal fin Apteronotus can move in any direction. Just like the loach family the Ghost Knifefish has no scales and is therefore more sensitive to diseases and water parameters. So we would highly recommend a UV steriliser for filtration.

Black Ghost Knifefish are carnivores. In the wild, they feed on insect larvae, juveniles and small fish and worms.  They love blood worm, brine shrimp or black worms.
