Ok, so I did some research on the goby tank idea and I wanted to run this by everyone.
I'm thinking of the following goby:
Green Clown Goby
Catalina Goby
Two Spot Goby
I'm estimating somewhere in the neighborhood of 15lbs of rock, 2"-3" substrate (aragonite), mainly zoas and ricordias for coral. I plan on putting some sand and cheato in the refugium.
