had to move the trops back to the 120g after aggression from the gator. the 120 really looks bursting now. haha. i am probably going to let 3 of the 6 trops go to reduce the strain on that tank so they have a little more space. i had hoped all the gars could go into the big tank before i enlist so that it would be easier to manage all the fishes, but looks like it's not going to happen
