Greeting fellow MFK'ers,

I recently got an opportunity to own one of my dream fish: and ATF, specifically the Brevis (sorry again Chix). The only problem right now is that I've had to combine my largest and most aggressive fish into one tank. Currently my 12" Mala wolf is living in the same tank as my 10" Odoe and my 23" Silver aro. I'm not too worried about the silver, but I am scared for my Odoe.
Last night I got to watch my wolf perform dominance displays every time one of the other fish got near him (he did that thing where he kind of vibrates like he's about to strike)

So far no blood has been spilt, but I'm wondering if I'm just begging for trouble with this combo. I was hoping that since they are all so large that displays of aggression would be enough, and they wouldn't have to brawl.

Anyone here have luck/experience keeping several super aggressive fish together?

Sorry, should have mentioned that. These fish are all in a 6x2x2 180 gallon.

Tiny bump with an update: I'm still seeing my Mala do his aggressive wiggle-dances, but no one has taken a swing at any of their tank mates yet.

I guess I'll just keep everyone well fed, and leave the decorations I have in place to allow the fish to hide every now and then.

Still would greatly appreciate any input from people who've kept large fish together.
