The Tridacna maxima (Pink-Purple) is a visually striking giant clam species prized for its vibrant pink and purple mantle colours. At 13cm, this clam is suitable for experienced marine aquarists with established reef tanks.
Care Level: Moderate care is required to maintain optimal health. This species relies heavily on photosynthetic symbiotic algae (zooxanthellae) within its tissues, so stable water parameters and appropriate lighting are essential.
Feeding: While Tridacna maxima primarily obtains nutrition through photosynthesis, it benefits from supplemental feeding of phytoplankton or specialised clam foods to support growth and vitality.
Lighting Requirements: Moderate to high lighting is recommended, ideally provided by LED or T5 reef lighting systems that support photosynthesis without causing stress.
Water Flow: Moderate water flow is ideal to ensure nutrient exchange and prevent sediment accumulation on the clam’s mantle.
Placement: Position the clam on a stable, hard substrate such as live rock or specialised clam bases in the lower to middle sections of the aquarium to avoid excessive light or flow.
Compatibility & Reef Safety: This clam is reef safe and compatible with most peaceful reef inhabitants. Avoid housing with aggressive fish or invertebrates that may nip at the mantle.
Minimum Tank Size: A minimum of 120 litres (approximately 30 gallons) is recommended to provide stable water conditions and space.
Origin: Not Provided.
Maximum Size: Tridacna maxima can grow up to 20cm in captivity under optimal conditions.
