Appearance & Physical Traits

• Coloration & Pattern: Cerith Snails possess elongated, spiral-shaped shells with coloration that can vary, often displaying shades of black, green, or white.
• Body Shape & Structure: Their distinctive elongated spiral shells provide both protection and camouflage within the aquarium environment.

Habitat & Environmental Needs

• Minimum Tank Size: Suitable for nano tanks as small as 5 gallons (19 liters), but thrive in larger, well-established aquariums.
• Water Temperature: Prefer temperatures between 74°F and 80°F (23°C to 27°C).
• pH Level: Maintain between 8.1 and 8.4.
• Specific Gravity: Optimal range is 1.023 to 1.025.
• Aquascape: Provide ample live rock and a sandy substrate to offer grazing surfaces and burrowing opportunities.

Diet & Feeding

• Diet Type: Omnivorous; primarily consumes algae and detritus.
• Preferred Foods: Feeds on various types of algae, detritus, and uneaten fish food.
• Feeding Frequency: In a well-established aquarium with sufficient algae and detritus, they typically do not require supplemental feeding.

Behavior & Compatibility

• Temperament: Peaceful and non-aggressive; spends much of the day burrowed in the substrate or grazing on surfaces.
• Social Behavior: Compatible with a wide range of reef-safe fish and invertebrates.
• Tank Mate Compatibility: Avoid housing with aggressive predators, such as certain crabs and fish species like Triggerfish and Pufferfish, which may prey on snails.
• Activity Level: Primarily nocturnal; often burrows during the day and becomes active at night.

Care Considerations & Additional Notes

• Ease of Care: Easy; they are hardy and adaptable, making them suitable for various marine aquarium setups.
• Special Requirements: Sensitive to high nitrate levels and copper-based medications; ensure water parameters are stable and within recommended ranges.
• Breeding Info: Breeding in captivity is challenging and not commonly achieved.
• Additional Notes: Cerith Snails play a vital role in maintaining aquarium cleanliness by consuming algae and detritus, as well as aerating the substrate through their burrowing behavior.
