they dont bother the gar at all.
they are still shorter than the gar, so hopefully it will stay that way when they are larger, which wont be long.
the tank doesn't have much in it, so there is plenty of space to eat and hide.
if i do see problems in the future, like most people, i would simply move the gar to another tank while my bass outgrow that 120, then gar back into 120
