Tridacna Clams should be added to well established aquariums with a sandy or small gravel bottomed aquarium. They should also be provided strong lighting, good water flow and the addition of calcium, strontium and iodine for long term success. Tridacna Clams have the ability to detect light changes with the eye spots on their mantles outer edge. Tridacna Clams receive most of their nutrients from photosynthesis.
