I've never been particularly good at this, but I think idea is to turn the Short Tempered Player's anger towards you, so that the fish don't feel so uneasy. Next time he starts berating the fish, start telling him that the fish played fine and that his play was horrible (bonus points if you can give the fish bad ideas at the same time). i.e. "xx played just fine - why were you raising AK UTG anyway? Don't you know its a drawing hand?" Chances are good that he'll forget all about the fish and will go crazy yelling at you because you dared to question his skills. Its still not a great atmosphere for the fish to lose money in, but hopefully they won't feel threatened anymore.
