Tridacna maxima, commonly known as the Tear Drop clam, is a captivating addition to mature marine reef aquariums. This small clam, reaching approximately 5cm in size, is prized for its vibrant mantle patterns and symbiotic relationship with photosynthetic algae.
Care Level: Moderate to advanced. Requires stable water parameters and strong lighting.
Feeding: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from supplemental feeding of phytoplankton or specialised clam foods to support growth and health.
Lighting: High-intensity lighting is essential to support photosynthesis. LED or metal halide lighting systems that provide strong PAR values are recommended.
Water Flow: Moderate, indirect water flow is ideal to ensure nutrient exchange without causing tissue damage.
Placement: Position on a stable substrate or rockwork in a well-lit area. Avoid placing near aggressive corals or in direct strong currents.
Compatibility: Reef safe with caution. Generally peaceful but can be sensitive to predatory fish and invertebrates. Avoid housing with clam-eating species.
Tank Size: Minimum 100 litres recommended to maintain stable water quality and adequate space.
Origin: Not Provided.
Maximum Size: Typically up to 15cm in mature specimens, though this listing is for a 5cm individual.
Regular water testing and maintenance are crucial to ensure optimal calcium, alkalinity, and magnesium levels for shell growth. Avoid sudden changes in water chemistry and temperature.
