Lungfish have changed very little in appearance since they first evolve over 400 million years ago. They range in size from 60 to 200 cm. The African lungfish has two lungs which enables them to breath when the water has dried up. There are four African lungfish species. The Protopterus annectens, however is the most common in aquariums. Lungfish are carnivores and are best kept in their own tank. They are considered to be fearless and they will attack almost anything that moves, including the hands of humans. Lungfish are rarely imported and they may be considered illegal in some states. The Lungfish can survive in almost any type of water conditions, as well as an area that has a low supply of oxygen
