Centipede Knifefish (Steatogenys duidae)


A peaceful and cryptic knifefish species, the Centipede or Sierra Knife is found throughout much of the Amazon basin where it is found in shallow water areas, usually among leaf litter. They feed on insect larvae and crustaceans in the wild but in the aquarium usually take to frozen foods very quickly. A social species, they are best kept in groups in the aquarium and should be provided with plenty of cover in the form of driftwood and leaf litter. This species is shy by nature and tends to feed at night or in dim lighting, so tankmates if any should be chosen carefully as they are easily outcompeted for food by fast moving fish or more aggressive eaters.
