I have a 6-7 inch Jar Aro I think he attacked anyone that came close, if any fish got near him he would beat them up, I also had a smaller 4inch Jar aro in there and he killed that one before I could get him into the other tank =(

He's very active and eats a lot, he just has no killer instinct or aggression.
