Name: Spider Stromb Snail / Spider Conch - In-store pickup only

Scientific Name: Lambis spp. (commonly Lambis lambis)

Description: A fascinating and distinctive marine snail recognised for its spectacular shell featuring long, finger-like projections that resemble spider legs. Spider Stromb Snails display beautiful shades of cream, orange, red and brown, making them an attractive addition to marine aquariums. These active bottom-dwelling molluscs spend much of their time grazing across sandy substrates, searching for algae, biofilm and organic matter. Their unusual appearance and interesting movements make them a unique addition to larger marine aquariums.

Origin: Indo-Pacific region, including northern Australia, Indonesia, the Philippines and tropical waters throughout Southeast Asia and the Pacific Ocean.

pH: Approximately 8.1–8.4

Temperature: Around 24–27°C

Adult Size: Approximately 15–25 cm, including shell projections, depending on species.

Lifespan: Approximately 3–5 years or potentially longer under suitable conditions. Species-specific lifespan information is limited.

Food: Primarily herbivorous and detritivorous. Feeds on microalgae, diatoms, biofilm and organic material found on sandy substrates. In established aquariums, they graze naturally throughout the day. Supplementary feeding with marine algae wafers, dried seaweed and suitable herbivore foods may be required if natural food sources are insufficient.

Compatibility: Generally peaceful and reef-safe, making them suitable for larger marine aquariums containing peaceful fish, corals and compatible invertebrates. Spider Stromb Snails do not normally harm healthy corals or other aquarium inhabitants. Avoid keeping them with predatory fish such as large Triggerfish, Puffers and Wrasses that feed on molluscs, as well as large predatory crabs. Their large size and extended shell projections require sufficient space to move freely without becoming trapped among rockwork.

Habitat: A mature, well-established marine aquarium with extensive open sandy areas for grazing and movement. Spider Stromb Snails prefer a fine to medium sand substrate and stable marine water conditions. Provide a specific gravity of approximately 1.023–1.026, good water quality and adequate calcium and alkalinity to support shell development. Open sandbeds are particularly important, as these snails can have difficulty navigating densely packed rockwork.  Avoid copper-based medications, as these are toxic to marine invertebrates.
