Do algae eaters and chichlids go together?

I don't know of any algae eating 'sucking catfish' that can be mixed with African Cichlids but some of the Malawi species of cichlid are Algae eaters I believe. As far as the other cichlids from the Americas and the Amazon goes, Plecostomus sp. can usually fit in with them OK. provided you make sure they all are of a similar size.
