The Squamosa Clam is also referred to as the Scaled Clam. Its species name squamosa is the Latin word for scale. The numerous rows of large scales over its entire shell are often used as shelter by other organisms, such as small crabs, other clams, and other invertebrates. The shell is symmetrical, and the matching growth pattern in its shell allows it to close together very tightly when it needs to. The Squamosa Clam is often found living amongst Acropora coral, anchored by its byssal filaments. It has a wide byssal opening and long tentacles surrounding its incurrent siphon. The Squamosa Clam can grow up to 12 inches or larger in the home aquarium.
The Squamosa Clam is hardy and less demanding of high intensity light. Even so, bright light supplied by halide lamps will help it grow and keep its intense colors. The type of lamp will depend on the depth of the tank and the position of the clam. A daylight fluorescent tube is also recommended. The Squamosa Clam requires calcium levels of 400-480 mg/L, and a carbon hardness of 7 to 12 degrees. Proper levels of strontium and iodine are also needed.
The Squamosa Clam relies heavily on the photosynthesis of the zooxanthellae cells growing in its mantle. However, All clams also require micro foods designed for filter feeders, especially when small. Offer phytoplankton and other micro-foods, such as Marine Snow.
