I'm about to start setting up my new(sorta) 180g craigslist tank.. Currently have a cpl pbass and a silver aro.. Really thinking about gearing the tank more for the pbass (plants, driftwood.. you know dieselmacks tanks caused this) but cant imagine getting rid of my arowana.. so the question really is with the aro hanging out at the top, would a bunch of floating plants be a problem for him? Aside from hiding food from him which i dont see as much as a problem as i almost always find myself watching them eat, it would be easy for me to just move the pellets out. Thanks in advance.
