Like Nicki said it all depends on the pleco...some can try and eat the slime coat off of an oscar during the night and some are perfectly fine with oscars and never bother them. Just keep a close eye on everyone if you get one just in case.
x2, i have many plecos and they never hurt any other fish.
I love plecos but my opinion may change if one of them sucked on any of my other fish.
If you have 2 big plecos, they may fight eachother, for they get territorial in the confined space of a tank.
