The Tridacna maxima (Greenish) is a captivating species of giant clam prized for its vibrant greenish mantle and manageable size of approximately 11cm. This clam is an excellent addition to established reef aquariums, offering both aesthetic appeal and ecological benefits.
Care Level: Moderate – requires stable water parameters and moderate to strong lighting.
Feeding: Primarily photosynthetic, relying on symbiotic zooxanthellae algae within its tissues. Supplementary feeding with phytoplankton or specialised clam foods can promote growth and health.
Compatibility: Reef safe with most invertebrates and fish. Avoid housing with aggressive or clam-nipping species.
Lighting: Moderate to high intensity lighting is essential to support photosynthesis. LED or T5 lighting systems designed for reef tanks are suitable.
Water Flow: Moderate water flow helps maintain cleanliness around the clam without causing tissue damage.
Placement: Position on a stable, hard substrate such as rockwork or sand bed in a well-lit area. Ensure the clam is secure to prevent movement.
Tank Size: Minimum 120 litres (approximately 30 gallons) to provide adequate space and water quality stability.
Regular monitoring of water parameters including calcium, alkalinity, and magnesium is recommended to support shell growth and overall health.
