Common name: Fluted giant clam
General information
The Fluted Giant Clam, scientifically known as Tridacna squamosa, is a species of bivalve mollusk in the family Cardiidae. It is one of the larger clam species, known for its distinctive scaly flutes on the shell which give it its common name. These clams are not only admired for their impressive size and beauty but also for their role in coral reef ecosystems as biofilters and contributors to the reef structure.

Care
Tridacna squamosa requires stable water conditions and intense lighting to thrive in captivity. They host symbiotic algae, zooxanthellae, which provide them with much of their nutritional needs through photosynthesis. However, they also benefit from supplemental feeding of phytoplankton and other fine particulate foods. It's crucial to place them on a stable substrate or rock where they can attach themselves securely.
Reproduction
In the wild, Fluted Giant Clams reproduce through broadcast spawning, where eggs and sperm are released into the water column. In the aquarium, breeding these clams can be challenging, but it is possible under optimal conditions. The larvae require specialized care and appropriate food sources to develop properly.
Symbiosis
The symbiotic relationship between Tridacna squamosa and the zooxanthellae algae is essential for the clam's survival. The algae reside within the clam's tissues, and the clam provides them with a protected environment and nutrients. In return, the algae produce oxygen and organic compounds that nourish the clam.
Habitat
Fluted Giant Clams are found in the warm waters of the Indo-Pacific region, typically in shallow coral reefs where sunlight is abundant. They prefer areas with moderate to strong water flow, which helps in the exchange of nutrients and removal of waste products.
