Hate to do this, but this fish is just too scary to throw in my big tank. 10 inch armatus eating frozen tilapia and living with a 12" bass and 4" datnoid. I used to have it with a bunch of 6-8" bass and they were doing fine together. I tried putting a 4" blind bass with it and the armatus killed it. $180 pick up in orange county, this guy is close to flawless if not flawless
