Black ghost knife fish (Apteronotus albifrons) primarily excrete waste in the form of ammonia, which is typical for many Freshwater Fish. Ammonia is released into the water through their gills and in their feces. Maintaining good water quality is essential for their health, as high ammonia levels can be toxic. Regular water changes and filtration are important for keeping their environment clean.
