I'm amazed people actually find it entertaining and think it's normal..
Some points I made and posted (if the comment ever is approved) so sane people know this is wrong.
1. NEVER ever mix tiger barbs with bettas, no wonder the betta got sick.
2. AND he got goldfish in the tank, there next when the barbs rip there fins I saw 1 already with hardly any tail.
3. If the betta was sick, in most cases put it in it's own tank, and if you know anything about fish i'm sure it could recover. I dont listen to pet stores usually on betta care.
4. Why would you feed a Sick fish to your healthy fish, common sense! The healthy fish can contract any disease it may have had.
5- There are humane ways to kill a fish, obviously this person has mental problems. Not to mention the fish was probably drowning, couldnt get up for air.
I flagged the video.
OMG it's playing to the little mermaid, what a psycho! Next he'll be like the guy in Saw, but in real life!
