Nassarius sp. also known as the Nassarius or Zombie snails, the shell shows mostly brown with ridges or bumps and can grow up to 3cm in length.
Nassarius Snails should be added to well established aquariums with a deep sand bed for burying themselves in search of food. Invertebrates do not tolerate copper medications. Nassarius Snails are great for beginner hobbyists as they are easy to care for, peaceful and reef safe.
