The Nassarius Snail, Nassarius sp., is an excellent reef scavenger. Their trunk-like tubes extend from curved shells while searching the sand, tank wall, and rock for microfauna prey. Nassarius Snails are capable sand-sifters as they can sometimes burrow in search of food, often detritus. Nassarius Snails require minimal attention and will thrive without any care in established reef tanks with plentiful live rock and algae. Overall, these snails are incredibly beneficial and are often instrumental in keeping tanks clean and operational. This package contains 50 of the Assorted Sand Sifting Nassarius Snails - Baja, or Nassarius Snail Caribbean.
