Care guide, husbandry, breeding, disease, sourcing, and tankmate intelligence on Magicus Snail - written by the Fast Aquatics editorial team and cross-verified against vendor records on the live marketplace.
Magicus Snail (Cerithium nodulosum) is a marine invertebrate kept by aquarists for reef-tank cleanup, biological control of pests, or aesthetic display. Hardy and forgiving of typical beginner mistakes when given proper water chemistry.
Where Magicus Snail comes from
Magicus Snail (Cerithium nodulosum) is native to Indo-Pacific reef ecosystems, with wild populations distributed across coral reefs, sandy lagoons, and rocky tide pools. Captive specimens are typically wild-collected; some species are starting to be aquacultured but most Magicus Snail sold today still comes from wild reef collection. Sustainable sourcing matters - look for vendors who can verify their collection practices, and consider aquacultured alternatives when available.
Magicus Snail tank size and setup
Magicus Snail requires a minimum of 20 gallons for healthy adults. The minimum is based on the species' adult size (2 inches), territorial range, and behavior pattern. Most Magicus Snail sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Magicus Snail setup: mature reef tank with stable parameters, live rock for cover, sandbed substrate (1-2"), reef-grade lighting if photosynthetic, and a fully-cycled biological filter at least 6 weeks old. Newly-cycled tanks under 6 weeks crash the parameters that Magicus Snail depends on.
Magicus Snail requires standard reef parameters held tightly stable: Temperature: 76-80°F (24-27°C) Specific gravity: 1.025 (refractometer-measured) pH: 8.1-8.4 Alkalinity: 8-9 dKH Calcium: 420-450 ppm Magnesium: 1300-1400 ppm Ammonia + nitrite: Both 0 ppm Nitrate: Under 10 ppm Copper: 0 (lethal to invertebrates)
Magicus Snail is sensitive to copper - never medicate the display tank with copper if Magicus Snail is present. Stable parameters beat perfect parameters.
What Magicus Snail eats
Magicus Snail is a detritivore. Eats uneaten food, fish waste, and biofilm. Generally finds enough food in a stocked tank without supplemental feeding. If population thins, drop in algae wafers or sinking pellets weekly. Feed Magicus Snail appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Magicus Snail tankmates and compatibility
Magicus Snail is generally peaceful and compatible with most reef community species. Avoid keeping with predatory fish that view inverts as food: large wrasses (especially halichoeres + thalassoma), triggerfish, pufferfish, and certain large angelfish. Multiple Magicus Snail can share a tank but compete for food.

Magicus Snail adult size and lifespan
Magicus Snail reaches 2 inches at adulthood with a captive lifespan of 2-4 years with proper care. Many marine inverts molt periodically; provide adequate calcium and a stable parameter regime to support healthy molts.
Can you breed Magicus Snail?
Magicus Snail breeding in captivity ranges from straightforward (some shrimp, snails) to nearly impossible (most starfish, urchins) due to pelagic larval requirements. Captive-bred specimens are increasingly available from sustainable aquaculture facilities; check with vendors before assuming wild-caught origin.
Common Magicus Snail diseases and problems
Magicus Snail is sensitive to copper, ammonia spikes, low oxygen, and rapid parameter swings. NEVER use copper medications in a tank with Magicus Snail. Symptoms of stress: reclusive behavior, color loss, refusal to feed, abnormal molting (incomplete or stuck molts). Most Magicus Snail deaths trace back to acclimation shock or parameter mismatch - drip-acclimate over 45-60 minutes when adding to a new tank.
Where to buy Magicus Snail online
Magicus Snail is sold at LFS (local fish stores), online retailers, and direct from breeders/wholesalers. Pricing varies widely by source, size, and quality:
