FLG are pretty mellow compared to other gar.. but silvery fish are usually a no go.. eventually they start takeing pot shots at them. I'm pretty sure Scotts gar killed an ATF, not sure what kind but he'll prolly share his experiances. IMO not a good match. I would also worry the Odoe might spook the gar as iir they are quite active fish. But I've never owned a Odoe or ATF in general, but I had bad experiances trying to comm a silver arrow with my gar in the past and have avoided silvery fish since, and many others have had bad experiences in general with silver fish and gar as a general rule.
