The Nassarius Snail is a little snail with a big appetite. This hungry
critter glides through your aquarium foraging for food. The Nassarius
Snail is an efficient scavenger and detritus eater and is the perfect
member of your reef aquarium cleanup crew. You will be pleased at how
quickly a small group of Nassarius Snails will clear detritus, uneaten
food, decaying organics, and fish waste.
The Nassarius Snail is a small scavenger with an oval, spiral shell that
resembles an olive pit. The Nassarius Snail likes to burrow in the
sand, usually with its long, tube-like siphon protruding from the
substrate. As it searches for food, the Nassarius Snail helps prevent
compaction and aerates aquarium substrate. Once the Nassarius snails senses food in the aquarium you will see them quickly “surface” from the sand bed.
The Nassarius Snail prefers an established aquarium with live rock and a
deep sand bed. It is sensitive to high nitrate levels and copper-based
medications.
Shells can differ from the photo.
