Yer that will work just keep your eye on the arrow chasing him , if he does give the jag one pipe that the arrow won't fit in and that he can defend from one end if your having trouble with pipe size and arrow fits in try angle it on side of tank so there's not much room for him to squeeze in , my jags quite big now 8" ish and hard only just thinkin about tanking his pipe out now coz they swim fine together its took a while though , good luck
