Chocolate Ghost Knifefish

The wild chocolate ghost knife comes from Colombia and grows to 24 inches. Very similar to the black ghost knife, these fish have not been bred in captivity. Chocolate ghosts do need some live feeders available - brine shrimp or live black worms would do. The local natives believe the black ghost knife fish holds the spirits of dead ancestors. Perhaps the chocolate ghost knife holds the spirits of eaten M&Ms.

Quick Facts

Care Guide

Tank setup: Give them hiding places like large tubes or caves, dim lighting, strong filtration and a tight lid. They are most active at night.

Feeding: Feed frozen foods like bloodworms and brine shrimp once a day, ideally in the evening. Some learn to take sinking pellets.

Tankmates: They will eat any fish that fits in their mouth. Keep them with large, peaceful fish.

Good to know: Ghost knifefish find their way in the dark using a weak electric field.
