He has a three tank QT system in his store. One of the three tanks are usually empty and that's where my fish will go. I just transferred all the fish from my 75 over, so I'm waiting a few weeks before I add anything else. I only plan to add one more "big" fish and some sort of schooling fish. Everyone at my LFS are pushing me to add more, but like you I want plenty of room for what's already in there. The norm quote I hear "Dude, it's 300 gallons, you can fit anything in there".. I just don't see it. I really want an Annularis Angel, but I'm on the fence.
