It is a filter feeder, and requires floating micro-plankton to be kept alive in the aquarium, and will do best in a mature reef aquarium system. It also needs proper calcium levels and alkalinity. It does not tolerate nitrates
The flame scallop is non-photosynthetic and requires supplementation with phytoplankton, and organic foods (Marine Snow or Selcon) provided by using a small pipette/straw to dispense the food upstream of its location. Each Red Flame Scallop needs to be fed individually.
IMO not at all easy to keep
