Care guide, husbandry, breeding, disease, sourcing, and tankmate intelligence on Squamosa Clam - written by the Fast Aquatics editorial team and cross-verified against vendor records on the live marketplace.
Squamosa Clam (Tridacna squamosa) is a marine invertebrate kept by aquarists for reef-tank cleanup, biological control of pests, or aesthetic display. Suitable for keepers with 6-12 months of experience and stable water chemistry.
Where Squamosa Clam comes from
Squamosa Clam (Tridacna squamosa) 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 Squamosa Clam 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.
Squamosa Clam tank size and setup
Squamosa Clam requires a minimum of 75 gallons for healthy adults. The minimum is based on the species' adult size (18 inches), territorial range, and behavior pattern. Most Squamosa Clam 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 Squamosa Clam 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 Squamosa Clam depends on.
Squamosa Clam 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)
Squamosa Clam is sensitive to copper - never medicate the display tank with copper if Squamosa Clam is present. Stable parameters beat perfect parameters.
What Squamosa Clam eats
Squamosa Clam is a photosynthetic + filter feeder. Powered primarily by photosynthesis through symbiotic zooxanthellae living in the tissue. Supplemental feeding of reef foods supports faster growth but is optional once light + parameters are dialed in. Feed Squamosa Clam appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Squamosa Clam tankmates and compatibility
Squamosa Clam 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 Squamosa Clam can share a tank but compete for food.

Squamosa Clam adult size and lifespan
Squamosa Clam reaches 18 inches at adulthood with a captive lifespan of 15-30 years with proper care. Many marine inverts molt periodically; provide adequate calcium and a stable parameter regime to support healthy molts.
Can you breed Squamosa Clam?
Squamosa Clam 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 Squamosa Clam diseases and problems
Squamosa Clam is sensitive to copper, ammonia spikes, low oxygen, and rapid parameter swings. NEVER use copper medications in a tank with Squamosa Clam. Symptoms of stress: reclusive behavior, color loss, refusal to feed, abnormal molting (incomplete or stuck molts). Most Squamosa Clam deaths trace back to acclimation shock or parameter mismatch - drip-acclimate over 45-60 minutes when adding to a new tank.
