Really depends on what needs to be cleaned up- if its excess food either will do a good job but they still need to be fed food for themselves not just scraps. Dojo loaches also need to be kept in groups. Dojos will keep the substrate aereated while cories won't. Yes your correct Cories need to be in a group also.
