Top Crown Snail

Top Crown Snail (commonly belonging to genera such as Lithopoma, e.g., Lithopoma undosum: 1. Appearance & Coloration Coloration: Their heavy, thick shells typically feature earthy tones mixed with purple, brownish-red, and grey, often heavily camouflaged by natural encrustations of coralline algae or marine buildup in home aquariums. Morphology: They get their common names ("Top Crown" or "Wavy Turban") from their distinctive, conic, spinning-top or turban-like shell structure. They also feature a muscular, patterned foot used to glide smoothly across glass and rockwork. Size: They are substantial scavengers, often growing anywhere from 2 to 6 inches depending on the specific species. 2. Native Origin & Habitat Geography: Found in various warm coastal and reef regions, with specific varieties originating from the Eastern Pacific and Indo-Pacific waters. Environment: Inhabits rocky reef structures, sand flats, and rubble zones where they can graze on natural algae and find shelter in crevices. 3. Tank Requirements Minimum Tank Size: Best suited for aquariums of 30 to 40 gallons or larger to ensure there is enough surface area and rockwork to sustain their constant grazing habits. Water Parameters: Temperature: 72°F – 78°F (22°C – 26°C) Salinity (Specific Gravity): 1.020 – 1.025 pH: 8.1 – 8.4 Handling Note: Like many large marine snails, they have a sturdy build, but if they happen to flip onto their backs on an open sand bed, they benefit from rockwork layouts that help them right themselves. 4. Diet & Feeding Natural Diet: Dedicated herbivores that scour rockwork and glass surfaces for organic matter. Captive Diet: Highly prized cleaning crew members. They voraciously consume nuisance microalgae, hair algae, diatoms, and cyanobacteria. If natural algae levels run low in a mature tank, supplement their diet with dried seaweed or algae wafers. 5. Reef Compatibility Status: Reef Safe Behavior: Completely safe with corals, clams, and invertebrates. They will not damage or nip at sessile reef life, though their large size means they can occasionally nudge loose, unattached frag plugs out of place while climbing over structures. 6. Temperament & Tank Mates Temperament: Completely peaceful, slow-moving, and docile. Compatibility: Excellent community cleanup crew addition. They coexist peacefully with virtually all non-aggressive fish, invertebrates, and corals. Avoid housing them with large, predatory shell-crushing fish or aggressive hermit crabs that might view them as targets for their shells.
