S. Eupterus in SA/CA tank?

[Tilapia-mariae]

I have an s.eupterus that I wanted to get out of my gf's community tank because its starting to get vicious, its about 5" long. I was floating the bag and my oscar bit the bag fairly aggressively. Do I just put him in and hope I don't have to do delicate removal of spines from my oscar or will he get a closer sniff and think, 'no thats not tasty'.

Thanks

whats the size of the oscar?
i've never kept them with oscar, but i have had them in tropical tanks, as well as cichlid tanks with no issues (they had smaller and larger tankmates)

Oscar is about double his size. I have a festae the same size as the eupterus and he has no problems swimming around/neer the oscar. But im not comparing apples with apples.
