I wish my 3 fishies were like that, but mine are really lazy and the only time of the day that they're active is around 7:30 AM. Because that's when we feed them, and then they go after the food like they're crazy. xD One of them can be such an idiot, when it sees food it starts making so many bubbles, that it can't even see where the food drops in the water... :'D
This is REALLY cute. Amazing lil fishes *_* But may I call your attention to the light sorces. Try adding the spot light to their eyes according to the light position n.n Unless this is your style, it looks a little wrong to me. Sorry Its an amazing piece never the less.
