Funny idea, but fish too quickly broken

In the morning, swam small Nemo an hour in his glass around and my cats had thus had their fun. Times the paw times just sitting in the water next to it and watch the fish. So in short a complete success.

When I went to the evening show my friend the fish that swam the again half an hour ... now he's dead .. I can that thing probably tomorrow return directly again .. if I get it to me again, I honestly do not said. A pity.
