Nassarius Snail (Nassarius vibex) — Sand Stirrer and Detritus Cleaner

The Nassarius Snail is a must-have member of any healthy reef Clean-Up Crew (CUC). Known as the “sand sifter,” it lives buried beneath the substrate and emerges when food is detected — making it one of the most efficient detritus eaters in the reef aquarium.

Small, hardy, and highly active, Nassarius Snails consume leftover food, fish waste, and decaying organics before they can pollute your system. Their movement keeps the sand bed oxygenated and prevents harmful gas pockets from forming.

Why Choose Nassarius Snails

• Natural sand cleaners that aerate and refresh the substrate.
• Consume leftover food and organic waste before decomposition.
• Reef-safe, peaceful, and compatible with all invertebrates and fish.
• Known as “zombie snails” — they emerge from the sand when food hits the water.
• Perfect complement to hermits and algae grazers for a balanced ecosystem.

Kit Options Available

• 5-Pack: Suitable for nano reefs (5–10 gallons)
• 10-Pack: Ideal for 10–20 gallon AIO systems
