I just got the three other fish so they are still young and I was thinking of adding a bottomfeeder, and I know some cichlids can get along with catfish so I was just wondering?
A LARGE Featherfin may be OK, just make sure that there is no way it can fit in the Oscars mouth, or that's where it will end up.
Make sure you have the space for those aggressive fish, and plenty of cover for the catfish.

You're oscar and green terror will try to kill each other when they get older.
'Featherfin' anything is a bad idea to mix with fish that like to nip fins (the convict)
You can definitely keep a catfish of some type with large cichlids, I'd just look for something a little more durable.
Since they are younger they should be alright together.
