The Tridacna maxima (Greenish) is a visually striking giant clam species prized for its vibrant green hues and intricate mantle patterns. At 13cm, this clam is a medium-sized specimen suitable for experienced marine aquarists with established reef tanks.
Care Requirements: Tridacna maxima clams require strong, high-quality lighting such as metal halide, T5, or powerful LED systems to support their symbiotic zooxanthellae algae. Stable water parameters with optimal calcium (400-450 ppm), alkalinity (8-12 dKH), and magnesium (1250-1350 ppm) are essential for shell growth and overall health.
Feeding: While primarily photosynthetic, this clam benefits from supplemental feeding of phytoplankton or specialized clam foods, especially in lower light conditions or during acclimation.
Compatibility & Reef Safety: This species is reef safe and generally peaceful, but care should be taken to avoid placing it near aggressive corals or fish that may nip at its mantle. It thrives best when securely placed on a stable substrate or rockwork in moderate to low water flow areas to prevent mantle damage.
Placement: Position the clam where it receives direct, intense lighting but is protected from strong currents that could cause mantle retraction or injury.
With proper husbandry, the Tridacna maxima (Greenish) can be a long-lived and captivating addition to a mature reef aquarium.
