I really like the pbass / aro combo. The point brought up regarding spoking the aro is definitely true - esp. during feeding time, since my pbasses go buckwild.
But yeah.. i was concerned since when i introduced my lima SN which is about an inch larger than the pbasses in the growout tank - 60 gal, they kept going after it. Luckily the lima is hecka fast, where the pbasses even had problems catching it. I just don't want that to happen to my aro.
For those of you who have or do keep the aro/pbass combo, do your aro or pbass get nippy towards each other? My pbasses are always jocking for pecking order. lol. Never really bad, just hear a lot of splashes.
Else - maybe I can create some safe havens in the tank - ex: like a loose pseudo plastic plant wall as to buffer some of the excitement in the tank for my aro, instead of leaving the tank barren. lol.
