I have a Motoro Ray that I have had for over a year and the same place I got him from has another one and I want it. But, I want everyone's opinion. I have never had more than one ray and I am worried about how mine will react to another one. Mine is about 7 inches across the disk and the one I want is about 4 inches across the disk. My tank is a 120 but within the next 6 months or so I will be ordering a 240 or a 300 not sure which. So any advise is welcome! Thanks Jamie
