Tridanca crocea - The crocea or "boring" clam is known for being one of the most beautiful and intensely colored animal species on earth. The crocea is the smallest of the giant clam species, reaching about 6" in length. It comes in endlessly different colors and patterns, each as unique as a fingerprint. This diversity makes clam "gardens" spectacular sights in home aquariums. It does well with high lighting in the rockwork near the surface of aquariums. The common name is the boring clam because it secretes an acidic substance out of the foot opening to bore into rockwork. This gives the clam stability and structure to become a part of the reef scape.

Care

Clams require great amounts of calcium, alkalinity, and trace elements for growth and health. They tend to do well in aquariums that also have thriving Acropora and other SPS corals. A calculated dosing schedule and stable water parameters are necessities.
Though these clams receive most of their nutritional needs from the photosynthetic symbiotic zooxanthellae in their cells, they'll benefit from feedings of phytoplankton, particularly smaller clams.

Placement

Be sure to never tear the threadlike byssal filaments under the clam that it uses to attach to substrate, as damaging these filaments will cause great harm to the clam, and it likely won't recover. Since the clam can't be removed from the substrate once it attaches, many reefers use epoxy putty to create a "clam cradle" that the clam can attach to, making it easy to move around the aquarium if needed.

Although they do require intense lighting, take care to acclimate this clam to new lighting using your light's built-in acclimation mode or by placing the clam on the bottom of the tank and slowly moving it toward the surface over the course of about 30 or more days. Carefully observing the clam will help you determine when to move it closer toward the light, and any paleness or transparency means the clam is bleaching from being elevated toward the light too quickly and will need to be placed on the bottom again.
