ORA’s Giant Clams are born and raised at our clam farm located in the Marshall Islands. ORA’s Marshall Islands Mariculture Facility (MIMF) grows several species of Tridacna Clams including Tridacna maxima, T. squamosa and T. derasa.
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.
