Anyways, this is how I'd slowly add my stock:
Add crabs and snails first. After three weeks, add the first type of shrimp you want. After three weeks, add the second type of shrimp and so on until you have all your shrimp. After another three weeks, add any other inverts you want in the same kind of three week intervals. After another three weeks after invert stocking is complete, add the goby. After another three weeks, add the clowns. I'd start adding corals when you add your second shrimp species. I don't know what your set list of inverts are, so the schedule may not be totally accurate to you personally, but I'm sure you get what I'm saying.
