Intruduce a JD to my Oscar tank?

[GregRM]

Looking for thoughts.

I have a 15 month old 11 inch oscar in a tank with 5 very intimidated SDs.

I had to get rid of a GT at month 4 because the O was constantly attacking him (although the GT was the one who actually took a bite out of my O).

I get very little value out of the Sds as they are so skitish and cowardly.

Could I possibly introduce an adult JD to this mix? and eventually get rid of the Sds?

You should be able to but your O sounds like a real beast. How big's the tank?

My tank is 90 gals. He's gets really worked up at times that's for sure. But I don't think it's about hurting the other fish just letting them know who's boss.
