Select options Gilled African Lungfish (Protopterus amphibius) $254.99 – $299.99 The rarest species of lungfish in the hobby and an Aqua Imports exclusive, the African Gilled Lungfish originates in the freshwater streams and wetlands of East Africa. This species is the smallest of all the lungfish, growing to only 18-20″ in length, and is distinguished by the three external gills which it keeps into adulthood. These lungfish are extremely active and tolerant of a wide variety of water parameters. Like most of the African species in the genus Protopterus, they have powerful jaws and have a tendency to take bites out of tankmates – so they are best kept singly or with smaller, fast moving species like Congo Tetras or peaceful species of barbs. Although juvenile fish are primarily gray in color, rare photographs of adult specimens indicate they will develop a marbled pattern with heavy black spotting.These lungfish are enthusiastic feeders, and quickly learn to “beg” for food at the front of the tank – most will even hand feed. The specimens we offer have been carefully quarantined for several weeks and are actively feeding on a variety of frozen and prepared foods, including pellets.
