Escargot de Nassarius

The Nassarius Snail (Nassarius sp.) is a beneficial marine invertebrate renowned for its scavenging abilities and distinctive burrowing behavior. Its active role in substrate aeration and detritus consumption makes it a valuable addition to saltwater aquariums.

Essential Information:

• Common Names: Nassarius Snail, Nassa Mud Snail, Sand Snail
• Scientific Name: Nassarius sp.
• Family: Nassariidae
• Origin/Habitat: Found in sandy or muddy substrates in littoral zones worldwide.
• Maximum Size: Up to 0.75 inches (2 cm)
• Lifespan: Approximately 2 years
• Level of Difficulty: Easy; suitable for aquarists of all experience levels
• Reef Safe: Yes; they are considered reef-safe and beneficial for substrate health

Appearance & Physical Traits:

• Coloration & Pattern: Typically gray to brown shells with subtle patterns, aiding camouflage in sandy environments.
• Body Shape & Structure: Conical shells with a sharp point and flat base; elongated siphon used for breathing and feeding.

Habitat & Environmental Needs:

• Minimum Tank Size: Suitable for tanks with a deep sand bed and established live rock
• Water Temperature: 72°F - 80°F (22°C - 27°C)
• pH Level: 8.3 - 8.4
• Specific Gravity: 1.023 - 1.025
• Aquascape: Requires a deep sand bed and live rock for optimal substrate health and food availability

Diet & Feeding:

• Diet Type: Scavenger
• Preferred Foods: Detritus, uneaten food, and organic debris
• Feeding Frequency: Generally self-sufficient in established tanks; monitor their condition and supplement as needed.

Behavior & Compatibility:

• Temperament: Peaceful and non-aggressive
• Social Behavior: Solitary; does not require companions but can coexist with other peaceful tank inhabitants.
• Tank Mate Compatibility: Compatible with most reef-safe fish and invertebrates; avoid housing with predatory species that may harm them.
• Activity Level: Primarily nocturnal but may also be active during daylight hours.

Care Considerations & Additional Notes:

• Ease of Care: Hardy and adaptable, making them suitable for beginners; can tolerate a wide range of water parameters.
• Special Requirements: Ensure stable water parameters and avoid sudden changes in salinity or temperature; acclimate slowly when introducing to a new tank to prevent shock.
• Breeding Info: Breeding in captivity is uncommon; they are broadcast spawners, releasing eggs and sperm into the water column; successful breeding may require specific conditions, such as water quality and the presence of both sexes.
• Additional Notes: Regular monitoring of water quality is essential; ensure there is sufficient detritus and organic matter in the substrate to support their dietary needs, or be prepared to provide supplemental feeding.
