The Tear Drop Clam (Tridacna maxima) is a popular choice among marine aquarists seeking a vibrant and manageable giant clam species. At approximately 11cm, this clam displays beautiful mantle patterns and colours, adding a striking focal point to reef tanks.
Care Requirements: This species thrives under moderate to high lighting, ideally provided by LED or T5 aquarium lights designed for reef systems. Stable water parameters are essential, with a temperature range of 24-28°C, salinity of 1.023-1.025, and calcium levels maintained around 400-450 ppm to support shell growth.
Feeding: While Tridacna maxima relies heavily on photosynthetic symbiotic algae (zooxanthellae) within its tissues, supplemental feeding with phytoplankton or specialised clam foods is recommended, especially for younger specimens or in lower light conditions.
Compatibility and Reef Safety: This clam is reef safe and compatible with most peaceful reef inhabitants. Avoid placing it near aggressive corals or fish that may nip at its mantle. Provide a stable substrate or rock placement where the clam can securely attach.
Placement and Water Flow: Position the clam in a well-lit area with moderate water flow to ensure adequate nutrient and gas exchange without causing tissue damage.
Overall, the Tear Drop Clam is an excellent addition to mature reef aquariums, offering both aesthetic appeal and biological interest.
