Important Notes Black Ghost Knifefish are sensitive to poor water quality and require a well-established aquarium. As a scaleless fish, they can also be more sensitive to certain medications, so treatments should always be used with caution. Although shy initially, they often become surprisingly interactive once settled and may even learn to take food directly from their keeper.
