Mildly intrigued by a salt tank

[rudy]

I have a spare tank at my office.
It is one of those waterhome type tanks with the filtration above the tank and the lighting seems pretty good. I am mildly intrigued by the salt set ups and was wondering what I could do with this thing? How much it would take to set up and what could I put in it?

I like reef type tanks and also predators. Dwarf lion some form of trigger, or something of that nature.
