Lutosa Snail

Geographical Origin and Habitat: Common in the tropical Western Indo-Pacific, particularly along the coast of China, the South China Sea, and Taiwan. Inhabits shallow muddy and sandy bottoms.

Taxonomy: Member of the family Babyloniidae. Features a thick, heavy, oval-elongated shell that can reach 5-7 cm in length. Equipped with a brown horny operculum. Grows to 6 cm.

Social Behavior: Peaceful, nocturnal, and burrowing. Spends the daytime completely buried in the sand. Employs its long siphon to sense food, emerging quickly to locate organic matter.

Coloration and Sexual Dimorphism: Shell color has a cream or ivory base with a regular pattern of rectangular orange-brown spots arranged in spiral bands. No visible sexual dimorphism.

Tank Setup: Must be provided with a fine sand bed at least 2-3 inches deep to allow burrowing behavior. Suitable for aquariums of 15-20 gallons or larger.

Diet and Feeding: Carnivorous scavenger. Does not eat algae. Actively consumes meaty foods (fish, shrimp, clam pieces) and high-protein sinking pellets. Must be fed target foods.

Water Quality: Stable tropical marine parameters: SG 1.020-1.025, pH 8.1-8.4, temp 22-28°C. Highly sensitive to copper treatments and elevated nitrates.

Compatibility and Tankmates: 100% reef-safe. Beneficial for stirring and aerating the sand bed. Do not house with predatory fish that feed on snails (e.g. puffers or large wrasses).

Aquarium Breeding: Rare in aquariums. Lays egg capsules on hard surfaces, but larval stages are pelagic and do not survive standard aquarium filtration.

Risks and Diseases: Starvation if not provided with enough meaty foods. Low calcium or alkalinity levels leading to shell degradation. Sensitive to copper.
