cleaning what? left over food? If it's a single convict and doesn't have a mate you could some cory cats to help clean up left over food bits... If you plan on adding a mate later on I would go with a more armoured catfish like a Raphael Talking Cat (either striped or spotted).
BTW what sort of pleco is it? A common pleco will get way to big for your tank and if your current 'mess' is actually fish poop I would bet dollars to donuts the pleco is the real culprit!
As far as algae cleanup goes I like bushtnose (bristlenose) pleco's the best...
PS: You can add more serpae tetras if you want...
