I really wouldn't recommend any pleco in a 10g. The rubberlips do get to 5", and DPs are quite big waste producers, so I think you would have water quality problems in the future. DPs do need excellent water conditions, and putting a pleco in with them in a 10g is asking for sickness and stress.
Some DPs, a couple of otos and maybe a shrimp or two is a better idea.
