Actually those pictures were taken a few months ago and he did eat all of his tankmates except for the peacock eels and some large gouramis. He tried to eat the black angelfish that is in the one picture but we stopped him before he could finish. So we have a 75 gallon for my other fish.
Actually yes he swims up and down on the glass alot! He also loves to swim in the bubbles from the bubble bar I highly reccomend getting one if you dont have one allready it's so much fun to watch him play in there!
I had an atlantic ray that constantly swam up and down the glass and I am a little depressed that my motoro doesn't, thanks for the idea I will definatly get one!
