Sorry woochuck, I wasn't ignoring you, it is just that I have never kept one and didn't know if you were asking about the true gars or the fish sold as gars like hujetas or needle fish. True gars in general are supposedly fairly mellow with fish more than 1/2 their own size and the same is said to be true of aros but it depends on the individual fish, a freinds silver aro is a bully and picks on anything not bigger than it is.
