Crocea clams seem to be more demanding, then maximas - both of these will do fine in a 45 gallon and lighting is the big issue as indicated above. Deresa and squamosa clams can grow larger and are not as demanding. Be careful about getting real small clams -1-2 in - they often are much cheaper but have a lower survival rate. Also, remember that you will need to feed phytoplankton. Good luck
