Brown Turbo Snail

Geographical Origin and Habitat: Widely distributed in the tropical Indo-Pacific, from East Africa and the Red Sea to the Ryukyu Islands, Australia, and Polynesia. Inhabits shallow rocky reefs.

Taxonomy: Member of the family Turbinidae. Features a thick, globose shell with irregular spiral ribs and nodules giving it a rough texture, measuring 3-4.5 cm in diameter. Grows to 4 cm.

Social Behavior: Peaceful, primarily nocturnal, and strictly herbivorous. Spends the daytime sheltering in shaded crevices and emerges at night to graze on rockwork and glass. Cannot easily right itself if flipped.

Coloration and Sexual Dimorphism: Shell color is mottled brown, greenish-brown, or rusty-orange, often marked with irregular cream or beige patches. Operculum is grayish-white. No visible sexual dimorphism.

Tank Setup: Suitable for reef aquariums of 15-20 gallons or larger. Requires stable live rock structures with ample surface area for grazing. Avoid open sand expanses without rock support.

Diet and Feeding: Strictly herbivorous. Consumes green hair algae, diatoms, cyanobacteria, and film algae. Supplement with dried seaweed (nori sheets) if natural algae is depleted.

Water Quality: Stable reef parameters. Salinity SG 1.021-1.025, pH 8.1-8.4, temperature 22-28°C. Highly sensitive to copper treatments and sudden osmotic shocks.

Compatibility and Tankmates: 100% reef-safe. Excellent member of the clean-up crew (CUC). Compatible with peaceful fish and corals. May be targeted by hermits seeking replacement shells.

Aquarium Breeding: Broadcast spawner. Reproduction in home aquariums is extremely rare as pelagic larvae do not survive standard filtration systems.

Risks and Diseases: Starvation in overly clean aquariums. Death from being flipped over on sand; must be manually turned upright. Shell erosion in aquariums with low pH.
