Oscars are quite peaceful as cichlids go. I doubt they'd even touch the plec.
But the JD may cause problems with all your other fish (even the oscar).
So are you saying maybe i should drop the JD? I dont really want to but if it is a must i will do it. I though JD could live with an oscar maybe im wrong .....
I realized that clown plecs need wood in their diet so i dropped clown plec. I really want to keep 4 clown loaches and not full grown. Maybe at 5-6" I can keep them in my 30 gallon and once they get that big then switch em into my 275.
Does it sound good?
if you want, i can send you a bichir list
