Marble Ghost Knife – Natural Environment Aquatix

The Marble Ghost Knife is a striking freshwater aquarium fish prized for its sleek, translucent body and distinctive knife-like silhouette. Native to South American waters, this peaceful species glides gracefully through planted tanks, feeding primarily on small invertebrates and organic debris. Best kept in groups of 3 or more, they thrive in soft, slightly acidic water with plenty of hiding spots among plants and driftwood. Their nocturnal nature makes them ideal for community tanks seeking low-aggression inhabitants. Requires a minimum 20-gallon tank with gentle filtration to avoid stress. A captivating addition for experienced aquarists who appreciate subtle, elegant fish.
