I have a roughly 16 inch common pleco an I am planning to do an overhaul of the tank he is in and give it some character. Right now it lives with a handful of tetras, but I was interested if discus can live alongside common plecos. From descriptions given, common plecos sound like vicious omnivores sucking the slime coat off any large fish, hence little fish may be what I would stick with. Not sure if that is just a way to discourage buying them. Any other good tank mate suggestions, that seem to do well with them.
