Clown knife tank size???

[Lkeizm]

So after looking at different fish for my new 280G 72x30x30
I’ve came across the clown knife, is this tank size suitable to house one?
how are they with tank mates such as Oscars and similar sized cichlids and bichirs?

Tank size should be good. Should get along with oscars and bichirs.
