My sad old USB mini aquarium

 
I bought this USB mini aquarium years ago (maybe 2004 or 2005), and it was really nice when it still worked.. I just cleaned it, the other day, and refilled it, but it doesn't seem to work anymore =( The light goes on when I plug it in and switch it on, but nothing else happens.. The clown fish eventually went up a bit (compare the above pics..), but the blue one seems 'dead' - if fake fish can die, heh..

Below, a video from 2005, when it still worked;
