lemon oscars compatible with clown knife?

[fishfantastic]

I found 2 5" lemon oscars in a store for 9.99 CANADIAN. They were asking 29.00 apiece but they are out growing the stores tanks so they put them onsale.Would they be compatible with my 13" clown knife? Temporarily in a 75 gal tank by its self. Moving up to a 180 gal this summer when i finish my basement. If I wait they'll be gone. 10$ a piece for5" lemon oscars is stealing them IS IT NOT? They are gorgous and very healthy.

5" compared to 13" is a bit small. The CK might think it's lunch time.
