I bought my Motoro getting on 2 months ago now. He started swimming up an down the glass about 1 month ago. He's now starting to swim about without 'leaning' on anything (sand or side glass). He's getting on for about an 8 inch disk now and is in the process of growing a 2nd and loosing a stinger. My question is will he swim about more without the aid of glass or sand as he gets bigger as he looks awesome when he's in the middle of the water and I'd love to see more of it?
