Wasn't the most entertaining video, but I haven't got any problem with posting something like this. I think it is pathetic that people get so bent out of shape over it.
I would agree with Razzle though. I think I would just raise my own. Mice seem simple enough to raise, and I am sure the fish would be happier to have them hit the water alive.
Regardless, that is a good looking tank and some good looking fishies as well. I never really thought about the mess they leave behind. Is it a pain to cleanup after them?
