At some point anyway. The only ray I have is a Motoro and he's only about 6 inches. Pretty cool dude though and I'm already kind of attached to his personality. He's currently in a 180g with a couple of other fish who try to steal his food...which forces me to stand there and keep them away with a thin dowel rod. They just see the rod and stay away from the ray. So today I made a deal on a new tank for him. It's used and needs a little work but when it's done this ray will have his very own 360g tank. How cool is that? I think it's awesome and it totally makes my day! I'm hoping this will make water changes less frequent but we shall see. Maybe I should get a couple more rays once I get this 360g set up. This is going to be great!! But no more tanks after this. I'm maxed out for room unless I dig a pond into the floor like I was saying the other day.
