General notes: The Electric Scallop is a difficult to maintain but rewarding addition to a reef system. The 'lightning' flashes are actually a membrane in the scallops mantle that is a striking blue and gives the appearance that the clam actually has electrical current flowing through it's mouth! The Electric Scallop requires daily feedings of phytoplankton which are best target fed with all circulation stopped to ensure it gets enough. Best kept in well established aquarium. Does not appreciate high current. Can be nipped and harassed by clown gobies, blennies, shrimp, and most Angelfish and Butterfly fish. Will move to where it feels comfortable like a ledge or cave. Repeated attempts to move back into the light may cause animal distress.
