CLOUDED GHOST KNIFEFISH

👻 Clouded Ghost Knifefish (Adontosternarchus spp.) – Rare, Electric, and Mesmerizing

The Clouded Ghost Knifefish is a mysterious and rarely seen electric species in the aquarium trade, prized for its cloud-like patterns, eel-like body, and graceful swimming style. Unlike the more common Black Ghost Knifefish, this species is typically pale to silvery white with subtle markings that resemble swirling mist—earning it the “Clouded” nickname.

Native to deep, slow-flowing rivers of the Amazon Basin, this species uses weak electrical pulses to navigate and locate prey in low-light conditions. It’s a peaceful oddball that does best in dimly lit aquariums with plenty of hiding spaces and soft substrate.
