It is morally permissable in that there is essentially no choice in the matter-they have to eat, one way or another, and so it is either feed ur invert or let it die. There is, however, a choice as to whether or not you put two creatures that would rather escape than fight in some crappy little glass tank and let them tear each other to pieces for human entertainment. Surely you can see the difference.
The video isn't about eating, it's about fighting, for human entertainment. Comparing a predator/prey relationship to a contrived fighting match is not a valid comparison. When you are feeding a pet, you are doing something essential to their survival, using a small prey item that is quickly killed with no injury to the animal it is being fed to. When you pit two large, dangerous animals against each other, there is high potential for un-necessary injury, and worse still, this is being done for no better reason entertainment and enjoyment. Trying to say that feeding a cricket to a scorpion to keep it alive is the same as fighting a centipede and a tarantula is like saying that someone eating a hamburger is the same as bullfighting. Yes, the end result is identical - a dead animal. But whereas one serves a practical purpose, the other is done purely for amusement. That's where the "unethical" part comes in.
