Elephant Nose Knifefish (Sternarchorhynchus oxyrhynchus)


A large growing and unique knifefish, the Elephant Nose Knifefish is, as the name implies, distinguished by its elongated trunk which it uses to root in substrate to find food. They feed on insect larvae and crustaceans in the wild, but in the aquarium will generally accept small frozen foods like bloodworms or brine. Like most knifefish, they are shy and should be provided with plenty of cover in the form of driftwood and leaf litter in the aquarium.
