yea it should work fine as long as the glass isn't the kind you usaly buy a tank from petmarts or othe large chain store and some LFS becasue more then often the glass can't be drilled into. i'm not sure on what type of glass it is thought i'm sure somebody here knows.
True.. but that fish bridge does look cool. Also it's something you could probably make yourself from perspex - WITHOUT hacking holes in your tanks. Just need a little vacum pump and a valve fitted on the top of the bridge to suck the air out.
i was actually thinking of something along the line of a water bridge but instead of going over the frames just a cylinder connecting them in the middle of the side panes of glass
