For any other trigger species I wouldn't even bother asking. The reason I brought it up though is that Xanthichthys sp. triggers are supposed to be mostly planktonic feeders (upturned mouth). According to this:

So blue chin, crosshatch, sargassum ..and .. I forget the common name of the other 2 or 3 Xanthichthys species triggers .. would theoretically be better behaved? I was hoping to hear some specific experiences with the crosshatch trigger specifically. I am tempted to try this still,but at this point still reluctant to .. er .. pull the trigger on it just yet (ooh punny) until I hear some more anecdotal evidence..
