When people want to complain intelligence goes out the window. We all know if we don't like it no one should. After all the guy who made the video is probably a liar. The comment was only made to appease those who might read it and not see he is just lying. Everything we see now a days is cruel if it happens to animals. Lets face it we don't know if the fish in those tank felt they were being mistreated.
I personally am getting tired of these cruelty threads. If you don't like something fine but don't try and tell everyone to believe you. That was pointed out in this thread as most felt the setup was fine and I agree.
