Ah yes, I remember that Blue Phantom you were talking about
As Pure said, almost all plecos will get along as long as there is enough room. My Common and Gold Line sometimes go at each other a bit, but they each have their spots to run off to and hide in. I'm lucky at the moment that my Phantom is small and thus doesn't bother the other three.
I'm planning my next tank around plecos and their need for territory, so I can keep more. It's an important part of having them, so make sure you have decent space for each of them.
