The cultured Tridacna clams from ORA are grown at our clam farm in the Marshall Islands, the Marshall Islands Mariculture Facility (MIMF). There are four species of Tridacna Clams under cultivation at our facility. They are Tridacna maxima, T. squamosa, T. derasa and T. gigas.

Tridacna Clams are relatively easy to care for in aquarium conditions. All of the clams in this genus have symbiotic algae called zooxanthellae. These algae provide most of the food and nutrients the clams need to live. It is important to provide the necessary amount of light to keep their symbiotic algae flourishing. Some species, such as T. maxima, prefer to be on rock surfaces high in the tanks, close to the light. Others, such as T. squamosa and T. derasa, are "sand" clams and prefer to be on a sand bed on the bottom. Some aquarists supplement feed with commercial phytoplankton cultures. Tridacna clams do filter feed on this type of plankton, but do not depend on it.
